[PHP] Modulus and floating point...

2002-01-04 Thread Boget, Chris

Consider the following:

$number = 102.52;

echo $number % 50;
echo bcmod( $number, 50 );

in both cases, it's spitting out 2.  Why is it not spitting
out 2.52?  Is there a way I can get that information?
w/o having to parse the string, breaking it up, getting
the modulus and then adding it back into the end result...?

You can consider doing this:
$number=102.52;
$fraction=$number-floor($number);
$number=($number % 50)+$fraction;

Basically it's the exact solution you're suggesting, just that you don't
have to do any string stuff.

PHP's behaviour is normal - modulus is generally intended for
integers...
