What's the best way to get the fractional part of a float in PHP?

Question

How would you find the fractional part of a floating point number in PHP?

For example, if I have the value 1.25, I want to return 0.25.

Answer 1

Some of the preceding answers are partial. This, I believe, is what you need to handle all situations:

function getDecimalPart($floatNum) {
    return abs($floatNum - intval($floatNum));
}

$decimalPart = getDecimalPart($floatNum);
