  • regular expression for letters, numbers and - _ .

    - by Jorre
    I'm having trouble checking in PHP if a value is is any of the following combinations letters (upper or lowercase) numbers (0-9) underscore (_) dash (-) point (.) no spaces! or other characters a few examples: OK: "screen123.css" OK: "screen-new-file.css" OK: "screen_new.js" NOT OK: "screen new file.css" I guess I need a regex for this, since I need to throw an error when a give string has other characters in it than the ones mentioned above.

  • Fastest possible summing numbers up to N

    - by dada
    Okay so i need really FAST algorithm or code in C if you have any it would be nice. The task is to sum all numbers from 1 to N for a given number N (it can be negative number too), so i did the usual way (you know just summing with loop from 1 to N) but it's not fast enough - i need something faster, i guess that i need the fastest possible way to do this. If anyone could help me, please do. Thanks.

  • SQL: how to get the left 3 numbers from an int

    - by dmr
    I want to retrieve the left 3 numbers from an integer to be stored in a table. For example, if the int is 1234567, I want to retrieve 123. I want the second number (123) to also be an int; I don't want to convert anything to a string. (And yes, really I should be working with strings. But I don't have control over that aspect of the issue.) Thank you!

  • getting numbers from lines of text

    - by Flethuseo
    Hi everyone, I want to parse a text file, where I get numbers that are between parenthesis like this: 1 2 3 (4 - 7) 8 9 1 3 8 (7 - 8) 2 1 1 2 (8 - 10) 3 2 should return an array for each: array1: 4 7 8 array2: 7 8 10 I am thinking of using split for each line, like line.split("("), but that doesn't quite doing the trick.. I was wondering if there is something more sophisticated for the job. Any help appreciated, Ted

  • Floating point numbers in XML

    - by Jamie
    what is the best way to handle floating point numbers in XML? If I have, for instance: double a = 123.456; and I would like to keep it as <A> 123.456 </A> simply using ... myDoc.createTextNode(a.ToString()); is fine? Or should it be done with some Globalization stuff to make it region-independent?

  • Interesting task using random numbers only

    - by psihodelia
    Given any number of the random real numbers from the interval [0,1] is there exist any method to construct a floating point number with zero decimal part? Your algorithm can use only random() function calls and no variables or constants. No constants and variables are allowed, no type casting is allowed. You can use for/while, if/else or any other programming language operands.

  • LaTeX, Two columns, Listings and Numbers

    - by Valdor65
    Hi, I'm trying to get a report done and I have a small problem with the twocolums and the line numbering in listings. The text is on two columns, the listings can be on the two columns as well. If I put the number=left, the space between the columns is not sufficient and the text from the first column is written over. Is there any way to ask the listings to put the line numbers "outside" ? Thanks

  • Easiest way to calculate amount of even numbers in given range

    - by Fdr
    What is the simplest way to calculate the amount of even numbers in a range of unsigned integers? An example: if range is [0...4] then the answer is 3 (0,2,4) I'm having hard time to think of any simple way. The only solution I came up involved couple of if-statements. Is there a simple line of code that can do this without if-statements or ternary operators?

  • is it possible in javascript to create shortcuts with sequence like 123,345 instead of combo?

    - by frankB
    I already used some script to implement the shortcuts in my web page but i was wondering if could be possible to associate some combination not syncronic like Ctrl+X but more like a sequence typing 1..2..3 or any other combination to execute a script... lets assume this example: you have a long list with numbers: you could type 3..5...6, so you can go to the item 356 passing trough the item 3 then 35 then 356 more or less like when you type while selecting a select box i hope it was clear, id not easy to explain...
