Multiplication of floating numbers in php is giving unacceptable result. For example, multiplication of 0.023* 0.0034 * 0.11 is yielding 0.
I have an array containing 48 floating numbers less than 1. I want the product of all 48 numbers, any way to achieve this in PHP?

As for a wordaround, since you are multiplyting, I will suggest that you multiple all numbers with powers of ten first and then again divide the output accordingly!
