Script Preparation code:

var bigIntL = 1000000n
var bigIntM = 50n
var bigInt2 = 2n
var numberL = 1000000
var numberM = 50
var number2 = 2

Tests:

BigInt
a = bigIntL b = bigIntM c = a - b c = a % b c = a * b c = a + b c = bigInt2 ** b
Number
a = numberL b = numberM c = a - b c = a % b c = a * b c = a + b c = number2 ** b
