Hi List,
I'm having a problem with the behavior of the floor() function:
echo floor(327.03 * 100)."\n"; //prints "32702" and not "32703"!!
Sanity check:
var_dump(327.03 * 100); //prints "float(32703)" as expected
Any ideas why this happens, and how to work around it?
Thanks,
Mattias
i think u should read the manual about int and float:
http://www.php.net/manual/en/language.types.integer.php
http://www.php.net/manual/en/language.types.float.php#warn.float-precision

Thanks, I guess I needed to read that again. What confused me here was
that var_dump(327.03 * 100) returns the expected value and not something
like (float)32702.99999999999999...
Cheers,
Mattias
