Compare floats in php

Question

I want to compare two floats in PHP, like in this sample code:

$a = 0.17;
$b = 1 - 0.83; //0.17
if($a == $b ){
 echo \'a and b are same\';
}
else {
 echo \'a         


        

Answer 1

Or try to use bc math functions:

Result:

0.17 == 0.17 (core comp oper): bool(false)
0.17 == 0.17 (with bc func)  : bool(true)
