PHP unexpected result of float to int type cast

Question

I\'trying to convert a float to an int value in php:

var_dump((int)(39.3 * 100.0)); //Returns 3929 but should be 3930!
var_dump((int)(39.2 * 100.0)); //Retur         


        

Answer 1

// gives: int(3930)
var_dump(intval((39.3 * 100.0) . '')); 

or, for use with a function:

function floatToInteger ($fValue)
{
    return (intval(($fValue + 0) . ''));
}

// gives: int(3930)
var_dump(floatToInteger(39.3 * 100.0));
