number format

[KashKurcura]

Hello:

Can someone please tell me if it is possible to take a fraction and turn it into numerical value?

For example below are two situtations;

Example 1
$Var = "-½";
$NewVar = "-.5";

Example 2
$Var = "+1½";
$NewVar = "1.5";

Any help would be great!

Probably just do a string replace (or use regex) of such characters.

e.g.

$Var = "-½";
$NewVar = str_replace("½", ".5", $Var);

You would do the same for example 2.

I believe you can also just do:
echo( 1/2 * 1 );
numbers are stored as integers with decimals in PHP, so if you do some kind of math to force it to take it as a number it should be fine.

I dont think that will work, Pig, because we're dealing with special characters.

The string replacement assumes that the result will be treated as a numeric value.

This should do the trick, If anyone has a better idea please let me know!

   $Data = "10½";
   $Data = preg_replace('/\xBD/', '.5', $Data);
   $Data = preg_replace('/EVEN/i', '0', $Data);
   $Data = preg_replace('/^(\+)?(-?[0-9.]+)( \([+-][0-9.]+\))?$/', '\\2', $Data);
   echo "$Data";
