Difference

[rashmi_k28]

Hi,

 

Is there any way to differentiate between 0 and 0.00.

 

$a=0;

$b=0.00;

 

In a function I have to assign color 
function FCallback($aVal) {

    if( $aVal == 0 ) $c = "red";
    elseif( $aVal == '0.00' ) $c = "black";
    else $c="green";
    return array(3,"",$c);
}

 

But if aVal is 0 and 0.00 same color is printed. Is there anyway to differentiate between the two.

function FCallback($aVal) {

    if( strlen($aVal )== 1 ) $c = "red";
    elseif( strlen($aVal )== 4) $c = "black";
    else $c="green";
    return array(3,"",$c);
}

Hi there, yes there is, just use === for comparison (and I removed quotes around 0.00 as it's not a string):

 

<?php
function FCallback($aVal) {

    if( $aVal === 0 ) $c = "red";
    elseif( $aVal === 0.00 ) $c = "black";
    else $c="green";
    return array(3,"",$c);
}
?>
