If you really need to use a float you can always use one of these.
<?php
$dividend = 48;
$divisor = 1.25;
$divisor *= 100;
$dividend *= 100;
print $dividend % $divisor / 100; //returns 0.5 as expected
?>
Or if you want to be complicated or don't want to use too many 0s or too few 0s (i.e. you can
multiply by 10000000 for a float like 1.0000025)
<?php
$dividend = 48;
$divisor = 1.25;
$eds = explode('.', "$divisor");
$ch = strlen($eds[1]);
$value = pow(10, $ch);
$divisor *= $value;
$dividend *= $value;
print $dividend % $divisor / $value; //returns 0.5 as expected
?>
I tested both and they both work nicely.
