Returns the product of two numbers that are treated as 32-bit signed integers.
Syntax
Math.imul(x, y);
Parameters
x
Required. The first number.
y
Required. The second number.
Remarks
This function is used for compilers like Emscripten and Mandreel, which don't implement integer multiplication in the same way as JavaScript.
Example
The following code example shows how to multiply numbers using Math.imul.
var result1 = Math.imul(2, 5);
// result1 == 10
var result2 = Math.imul(Math.pow(2, 32) - 1, Math.pow(2, 32) - 2);
// result2 == 2
