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

Here is the solution for comparing floating points or decimal numbers

//$fd['someVal'] = 2.9;
//$i for loop variable steps 0.1
if((string)$fd['someVal']== (string)$i)
{
    //Equal
}

Cast a decimal variable to string and you will be fine.
