[SOLVED] Checking if a divided number isn't a fraction

[FrostiE]

Hey,

 

Was hoping you people could help me...

What I'm trying to do, is to check whether a divided number is a integer or a fraction. A number gets divided by a incrementing for integer.

 

I tried ctype_digit but it doesn't seem to work with any divided result.

 

If you could help, I would really appreciate it !

Use is_float() or is_int().

 

Orio.

what about

 

<?php
$x = 1.8;

if(is_int($x))
{
echo "integer ";
}else{
echo "fraction";
}
?>

 

EDIT: Ahh beat me

Or there's always the mod Arithmetic operator % (i.e. it computes the remainder). If the mod is anything other than 0 then it is not a whole number:

 

if ($x % $y) { echo "Fraction"; }

else { echo "Integer"; }

Ahh thanks ! Somehow managed to overlook the is_int function.
