Preventing floats/fractions numbers

[bachx]

I've been trying to check for the number types entered by the user in case they're floats or not with no luck. I don't want the user for example to be able to enter 0.6 or .9, only real numbers should be allowed. I've tried is_float(), is_int() and is_real() with no luck, they either allow all numbers or pervent all. Any ideas?

is_numeric()

You can try to convert what the user is typing in to an int using 1 of 2 methods:

 

Type casting

<?php
$x = 0.5;
print (int) $x;
?>

 

Function

<?php
$x = 0.5;
print intval ($x);
?>

I don't want to convert the user input, I want to simply prevent anything but integers. Is that possible? is_numeric(), nor the other functions I listed doesn't seem to do that.

yeah, but fyi real numbers are 1,2,4.3,6.23423.2/4,6/23 non real numbers are 5sqrt(-1) 654sqrt(-1) or 654i  f

 

Any way try

 

<?php
$num = $_POST['num'];
$round = round($num);
if ($round == $num && is_finite($round)){
echo "Its a non decimal number containing a finite value have fun.";
else{
echo "Its in valid size";
}
?>
