  • How to disable Excel's auto recognition of numbers and text

    - by Yin Zhu
    I used Python to generate a CSV file. But when I open it in Excel, Excel will auto recognize a string into a number if it could be converted. e.g.33E105, which is actually an ID, not a number. How to disable this in Excel while opening a CSV file? Or I need to resort to a excel-python library to output a excel file and specify the format myself? Thanks!

  • Encode complex number as RGB pixel

    - by Vi
    How is it better to encode a complex number into RGB pixel and vice versa? Probably (logarithm of) an absolute value goes to brightness and an argument goes to hue. Desaturated pixes should receive randomized argument in reverse transformation. Something like: 0 - (0,0,0) 1 - (255,0,0) -1 - (0,255,255) 0.5 - (128,0,0) i - (255,255,0) -i - (255,0,255) (0,0,0) - 0 (255,255,255) - e^(i * random) (128,128,128) - 0.5 * e^(i *random) (0,128,128) - -0.5 Are there ready-made formulas for that?

  • Convert scientific notation to decimal notation

    - by Ankur
    There is a similar question on SO which suggests using NumberFormat which is what I have done. I am using the parse() method of NumberFormat. public static void main(String[] args) throws ParseException{ DecToTime dtt = new DecToTime(); dtt.decToTime("1.930000000000E+02"); } public void decToTime(String angle) throws ParseException{ DecimalFormat dform = new DecimalFormat(); //ParsePosition pp = new ParsePosition(13); Number angleAsNumber = dform.parse(angle); System.out.println(angleAsNumber); } The result I get is 1.93 I didn't really expect this to work because 1.930000000000E+02 is a pretty unusual looking number, do I have to do some string parsing first to remove the zeros? Or is there a quick and elegant way?

  • Convert a string of numbers to a NSTimeInterval

    - by culov
    I know I must be over-complicating this because it NSTimeInterval is just a double, but I just can't seem to get this done properly since I have had very little exposure to objective c. the scenario is as follows: The data im pulling into the app contains two values, startTime and endTime, which are the epoch times in milliseconds. The variables that I want to hold these values are NSTimeInterval *start; NSTimeInterval *end; I decided to store them as NSTimeIntervals but im thinking that maybe i ought to store them as doubles because theres no need for NSTimeIntervals since comparisons can just be done with a primitive. Either way, I'd like to know what I'm missing in the following step, where I try to convert from string to NSTimeInterval: tempString = [truckArray objectAtIndex:2]; tempDouble = [tempString doubleValue]; Now it's safely stored as a double, but I can't get the value into an NSTimeInterval. How should this be accomplished? Thanks

  • Working with ieee format numbers in ARM

    - by Jake Sellers
    I'm trying to write an ARM program that will convert an ieee number to a TNS format number. TNS is a format used by some super computers, and is similar to ieee but different. I'm trying to use several masks to place the three different "part" of the ieee number in separate registers so I can move them around accordingly. Here is my unpack subroutine: UnpackIEEE LDR r1, SMASK ;load the sign bit mask into r1 LDR r2, EMASK ;load the exponent mask into r2 LDR r3, GMASK ;load the significand mask into r3 AND r4, r0, r1 ;apply sign mask to IEEE and save into r4 AND r5, r0, r2 ;apply exponent mask to IEEE and save into r5 AND r6, r0, r3 ;apply significand mask to IEEE and save into r6 MOV pc, r14 ;return And here are the masks and number declarations so you can understand: IEEE DCD 0x40300000 ;2.75 decimal or 01000000001100000000000000000000 binary SMASK DCD 0x80000000 ;Sign bit mask EMASK DCD 0x7F800000 ;Exponent mask GMASK DCD 0x007FFFFF ;Significand mask When I step through with the debugger, the results I get are not what I expect after working through it on paper. EDIT: What I mean, is that after the subroutine runs, registers 4, 5, and 6 all remain 0. I can't figure out why the masks are not working. I think I do not fully understand how the number is being stored in the register or using the masks wrong. Any help appreciated. If you need more info just ask. EDIT: entry point: Very simple, just trying to get these subroutines working. ENTRY LDR r1, IEEE ;load IEEE num into r1 BL UnpackIEEE ;call unpack sub SWI SWI_Exit ;finish

  • A solid nickname regexp

    - by iBram
    I want a regular expression to validate a nickname: 6 to 36 characters, it should contain at least one letter. Other allowed characters: 0-9 and underscores. This is what I have now: if(!preg_match('/^.*(?=\d{0,})(?=[a-zA-Z]{1,})(?=[a-zA-Z0-9_]{6,36}).*$/i', $value)){ echo 'bad'; } else{ echo 'good'; } This seems to work, but when a validate this strings for example: 11111111111a is not valid, but it should aaaaaaa!aaaa is valid, but it shouldn't Any ideas to make this regexp better?

  • C++ question on prime numbers.

    - by user278330
    Hello. I am trying to make a program that determines if the number is prime or composite. I have gotten thus far. Could you give me any ideas so that it will work? All primes will , however, because composites have values that are both r0 and r==0, they will always be classified as prime. How can I fix this? int main() { int pNumber, limit, x, r; limit = 0; x = 2; cout << "Please enter any positive integer: " ; cin >> pNumber; if (pNumber < 0) { cout << "Invalid. Negative Number. " << endl; return 0; } else if (pNumber == 0) { cout << "Invalid. Zero has an infinite number of divisors, and therefore neither composite nor prime." << endl; return 0; } else if (pNumber == 1) { cout << "Valid. However, one is neither prime nor composite" << endl; return 0; } else { while (limit < pNumber) { r = pNumber % x; x++; limit++; } if (r == 0) cout << "Your number is composite" << endl; else cout << "Your number is prime" << endl; } return 0; }

  • Getting consecutive version numbers from Hibernate's @Version usage once per transaction

    - by Cheradenine
    We use Hibernate with the following version definition for optimistic locking et. al: <version name="version" access="field" column="VERSION" type="long" unsaved-value="negative"/> This is fine and dandy; however, there is one small problem, which is that the first version for some entities is '0', and for others, it is '1'. Why this is happening, is that for some object graphs, an entity will be subject to both onSave and flushDirty - this is reasonable, such as if two object are circular dependencies. However, the version number gets incremented on both occasions, leading to the above '0' / '1' discrepancy. I'd really like the version number only to ever increment once per transaction. However, I can't see a simple way to do this in the hibernate versioning implementation, without hacking about with an Interceptor (which was how I generated a column value for version before, but I wanted hibernate to do it itself)..

  • "Nearly divisible"

    - by bobobobo
    I want to check if a floating point value is "nearly" a multiple of 32. E.g. 64.1 is "nearly" divisible by 32, and so is 63.9. Right now I'm doing this: #define NEARLY_DIVISIBLE 0.1f float offset = fmodf( val, 32.0f ) ; if( offset < NEARLY_DIVISIBLE ) { // its near from above } // if it was 63.9, then the remainder would be large, so add some then and check again else if( fmodf( val + 2*NEARLY_DIVISIBLE, 32.0f ) < NEARLY_DIVISIBLE ) { // its near from below } Got a better way to do this?

  • Tracing spoofed mobile phone numbers

    - by RaDeuX
    I am being harassed by some prank caller that is spoofing his/her number neither T-Mobile nor the police can do anything about it. I have been told from one of my friends that if I set up an Asterisk server, I can accomplish the tracing of the prank caller. I am hardly knowledgeable in terms of networking, so a lot of what they told me was filled with jargon I couldn't really understand. But first things first, I downloaded Asterisk 1.5.0 and was finally able to install it (had issues with partitioning... In the end I just had Asterisk hog the entire HDD space). I tried out Asterisk, and it was slightly complicated for me so I decided to install trixbox 2.8.0.4 instead. It looks very similar to Asterisk... I'm not entirely sure what to do from here. I know I have to get the server up and running, but do I need a PBX card or something to accomplish what I'm trying to do? I'm running trixbox on a laptop to minimize electricity usage. Also, will I have to open any ports for the server? I have limited administrative permissions because of my father who is very uncomfortable with opening ports.

  • Sorting List which has object that contains two string members that contains numbers

    - by Lemo
    I want to know the best solution for this my case here is that i am taking values from Excel sheet and pushing them to database field, sometimes that field might contain some strings (thats why I cant make my object members int / double) In my class below size is the variable responsible for showing size of files in bytes public class dataNameValue { public string Name { get; set; } public string Count { get; set; } public string Size { get; set; } } I wanted to sort the list by file Size something like List mylist = new List(); mylist = mylist.OrderByDescending(i = i.Size).ToList(); The problem is that if i sorted it without converting it to "int/double" first -- its not giving right results

  • Separating arguments to a function, in locales with comma as decimal marker

    - by Chris Pousset
    In locales, e.g. French, with comma as decimal indicator (where "5,2" means five and two-tenths), how do users separate function arguments from each other? For example, in many programming/scripting languages, I could specify MAX(1.5, X) in a EN-US locale. How do you avoid the ambiguity between the comma as decimal indicator, and as argument separator? In particular, I'm interested in how software that's perceived as user-friendly in the foreign locale does it. Obviously, it's a no-brainer to say, "thou shalt use decimal POINTs", but that's not particularly "friendly".

  • Android TextView Linkify problem with phone numbers and application version number

    - by Gaks
    I have a problem with TextView and autoLink feature. I have an about screen in my application with some information like support phone number, email address, website URL and application version in form like 01.01.01 After setting autoLink="all" on the textView, all values are linked fine - except that version number 01.01.01 is linked as the phone number as well. Is there some way to exclude this text fragment from linkifing?

  • Create WPF TextBox that accepts only numbers

    - by Elad
    I would like to create a TextBox that only accepts numeric values, in a specific range. What is the best way to implement such TextBox? I thought about deriving TextBox and to override the validation and coercion of the TextProperty. However, I am not sure how to do this, and I understand that deriving WPF control is generally not recommended. Edit: What I needed was a very basic textbox that filters out all key presses which are not digits. The easiest way to achieve it is to handle the TextBox.PreviewTextInput event: private void textBox_PreviewTextInput(object sender, TextCompositionEventArgs e) { int result; if (!validateStringAsNumber(e.Text,out result,false)) { e.Handled = true; } } (validateStringAsNumber is my function that primarily use Int.TryParse) Some of the suggested solutions are probably better, but for the simple functionality I needed this solution is the easiest and quickest to implement while sufficient for my needs.
