Benchmark: JavaScript number type benchmark

Script Preparation code:

var bigInt32 = 2n ** 24n;
var bigInt64 = 2n ** 40n;
var bigInt128 = 2n ** 80n;
var bigIntNum = 2n;

var int32 = 2 ** 10;
var int64 = 2 ** 40;
var float = Math.fround(2 ** 20);
var double = 2 ** 80;
var intNum = 2;

const imul = Math.imul
const fround = Math.fround

Tests:

BigInt (32)
let a = bigInt32; let b = bigIntNum; let c_sub, c_mod, c_mul, c_add; c_sub = a - b; c_mod = a % b; c_mul = a * b; c_add = a + b;
BigInt (64)
let a = bigInt64; let b = bigIntNum; let c_sub, c_mod, c_mul, c_add; c_sub = a - b; c_mod = a % b; c_mul = a * b; c_add = a + b;
BigInt (128)
let a = bigInt128; let b = bigIntNum; let c_sub, c_mod, c_mul, c_add; c_sub = a - b; c_mod = a % b; c_mul = a * b; c_add = a + b;
Number (Int32)
let a = int32; let b = intNum; let c_sub, c_mod, c_mul, c_add; c_sub = a - b; c_mod = a % b; c_mul = a * b; c_add = a + b;
Number (Int32 asm.js)
"use asm"; let a = int32 | 0; let b = intNum | 0; let c_sub, c_mod, c_mul, c_add; c_sub = (a - b) | 0; c_mod = (a % b) | 0; c_mul = imul(a, b); c_add = (a + b) | 0;
Number (maybe Int64)
let a = int64; let b = intNum; let c_sub, c_mod, c_mul, c_add; c_sub = a - b; c_mod = a % b; c_mul = a * b; c_add = a + b;
Number (Float asm.js)
"use asm"; let a = float; let b = fround(intNum); let c_sub, c_mod, c_mul, c_add; c_sub = fround(a - b); c_mod = fround(a % b); c_mul = fround(a * b); c_add = fround(a + b);
Number (Double)
let a = double; let b = intNum; let c_sub, c_mod, c_mul, c_add; c_sub = a - b; c_mod = a % b; c_mul = a * b; c_add = a + b;
