bitwise AND in Javascript with a 64 bit integer

Question

I am looking for a way of performing a bitwise AND on a 64 bit integer in JavaScript.

JavaScript will cast all of its double values into signed 32-bit integers to do

Answer 1

Here is code for AND int64 numbers, you can replace AND with other bitwise operation

function and(v1, v2) {
    var hi = 0x80000000;
    var low = 0x7fffffff;
    var hi1 = ~~(v1 / hi);
    var hi2 = ~~(v2 / hi);
    var low1 = v1 & low;
    var low2 = v2 & low;
    var h = hi1 & hi2;
    var l = low1 & low2;
    return h*hi + l;
}
