Description:
------------
int added by float ended as not equal to float equavalent value

Reproduce code:
---------------
//this output <empty>, not 1
echo isValidRange( 5.23, 1, 10, 0.01 );

//this output 1
//echo 5.23 == (1+4.23);



function isValidRange( $p_value, $p_start, $p_end, $p_step=1 )
{
    //reverse step
    if( $p_end < $p_start )
    {
        $p_step = -($p_step);
    }
    if( $p_step == 0.000000 )
    {
        raiseError(1, "Invalid step: " . $p_step);
    }
    for( $c = $p_start; $c <= $p_end; $c+=$p_step )
    {
        //this part caused the problem
        if( $p_value == $c )
        {
            return true;
        }
       //if change it to
       //if( $p_value."" == $c."" )
       // then it works! return true



    }
    return false;
}



Expected result:
----------------

Actual result:
--------------
