• Seeing double-cursor in 'recursive RDP'

  - by John

  I'm using a Virtual PC VM on my PC to connect to a remote PC using RDP over a VPN. It works just fine except that in the RDP session, I often see a double mouse cursor... I get a standard mouse-arrow and the context-specific cursor such as a caret or hourglass. It's not a big problem but rather annoying and I wondered if there's any way to fix it, or at least understand where it comes from? Is it because I'm effectively running one RDP session from inside another? My host PC runs W7, my local VM runs XP, and the remote PC access using RDP is W7. Thankyou for any help.

• Why Is ToString() Rounding My Double Value?

  - by user163757

  How do I prevent my double value from being rounded when converting to a string? I have tried both Convert.ToString and ToString() with the same result. For example my double may look something like 77.987654321, and the two strings conversions convert to to 77.98765. I need to keep the precision of the value as is.

• F#: how to create matrix of elements of any other type except Double

  - by Nike

  I'm a beginner in F#. I know that there is the way to create Double Matrix using PowerPack.dll: let B = matrix [ [ 1.0; 7.0 ]; [ 1.0; 3.0 ] ] How can I create matrix with elements of my own type (for example with [,] instead of Double), so it would look like: let B = matrix [ [ [1,2]; [3,4] ]; [ [7,8]; [5,6] ] ]

• need a regex to parse a csv file with double quotes in php

  - by Brandon G

  Trying to parse a csv file that has all the data wrapped in double quotes, because there may be commas in the double quotes. Looks like this: $songs = '"1, 2, 3, 4 (I Love You)","Plain White T's","CBE10-22",15,"CBE10-22","","","CB",984,"","10/05/10"'; $regResult = preg_match( "", $songs, $matches ); I can't figure out a regex that will return the data between the quotes as the matches. I'm sure there is some regex master that can help me with this.

• cocoa - converting a double to string

  - by Mike

  I have a double number and I would like to convert it to string. The number is, for example, something like 24.043333332154465777... but if I convert it to string using something like NSString *myString = [NSString stringWithFormat:@"%f", myDouble]; The string is just 24.043333 how do I get a full string the corresponds to the whole double number? What other methods do I have to convert this?

• Azure storage - double decimal point ignored on save

  - by Fabio Milheiro

  I have a value that is correctly stored in a property of an object, but when I save the changes to the Azure storage database, the double value is stored to the database ignoring the point (7.1000000003 is saved as 711). Also, the property is changed to 711.0. How do I solve this problem? The field is already set to double in the class and the database table.

• C precision of double: compiler dependent?

  - by yCalleecharan

  Hi,on my 32-bit machine (with an Intel T7700 duo core), I have 15 precision digits for both double and long double types for the C language. I compared the parameters LDBL_DIG for long doubles and DBL_DIG for doubles and they are both 15. I got these answers using MVS2008. I was wondering if these results can be compiler dependent or do they just depend on my processor? Thanks a lot...

• Fast double -> short conversion with clamping using SSE?

  - by gct

  Is there a fast way to cast double values to shorts (16 bits signed), currently I'm doing something like this: double dval = <sum junk> int16_t sval; if (val > int16_max) { sval = int16_max; } else if (val < int16_min) { sval = int16_min; } else sval = (int16_t)val; I suspect there's a fast way to do this using SSE that will be significantly more efficient.

• Extend precision of MySQL's double datatype?

  - by tim82

  I am trying to save the value "6.714285714285714" into a DOUBLE datatype field. Unfortunately it does not fit at all and is cutted by one char. Storing larger numbers becomes less precise. Already searched in the mysql manual and it seems to be that double is the most precise data type available. Anyone knows a practicable workaround? Sorry for my bad english and thx a lot!

• PHP array pointer craziness

  - by JMan

  I'm trying to create a "GetCurrentLevel" method that takes a point value as an input and returns what "Level" that corresponds to. I'm storing the Level = Points mapping in an array, but the array pointer is not moving logically when I use it a foreach loop. I've added echo statements for debugging. Here's my class definition: class Levels extends Model { protected $_map = array ( 'None' => 0, 'Bronze' => 50, 'Silver' => 200, 'Gold' => 500 ); public function __construct() { parent::__construct(); } public function GetCurrentLevel($points) { foreach ($this->_map as $name => $threshold) { echo "Level Name: $name<br/>"; echo "Level Threshold: $threshold<br/>"; echo "Current Level: " . key($this->_map) . "<br/>"; echo "Current Threshold: " . current($this->_map) . "<br/>"; if ($points < $threshold) /* Threshold is now above the points, so need to go back one level */ { $previousThreshold = prev($this->_map); echo "Previous Threshold: $previousThreshold<br/>"; echo "Final Level: " . key($this->_map) . "<br/>"; return key($this->_map); } echo "Go to next level <br/>"; } } And here is what I see when I call GetCurrentLevel(60): Level Name: None Level Threshold: 0 Current Level: Bronze //* Looks like foreach immediately moves the array pointer *// Current Threshold: 50 Go to next level Level Name: Bronze Level Threshold: 50 Current Level: Bronze //* WTF? Why hasn't the array pointer moved? *// Current Threshold: 50 Go to next level Level Name: Silver Level Threshold: 200 Current Level: Bronze //* WTF? Why hasn't the array pointer moved? *// Current Threshold: 50 Previous Threshold: 0 Final Level: None But the "Final Level" should be 'Bronze' since 60 points is above the 50 points needed for a Bronze medal, but below the 200 points needed for a Silver medal. Sorry for the long post. Thanks for your help!
