A workaround for floating-point number multiplication in JavaScript _javascript tips

Multiplying floating-point numbers in JavaScript is a fun thing to do.

There are many ways to multiply floating-point numbers, and here's a solution that I think is good for me:

Copy Code code as follows:
function fxf (f1, F2) {
F1 + = ';
F2 + = ';
var F1len = F1.split ('. ') [1].length,
F2len = F2.split ('. ') [1].length;

if (F1len) {
F1 = F1.replace ('. ', ');
}
if (F2len) {
F2 = F2.replace ('. ', ');
}
Return F1 * F2/MATH.POW (F1len + F2len);
};

Basic ideas

The basic idea is to turn the floating-point numbers into integers and divide them by the N-order of the equivalent 10. n is (the sum of the back lengths of two floating-point numbers).
