2
a = number1 b = number2 c = a - b c = a % b c = a * b c = a + b
3
a = pgMaxBigInt b = pgDiv c = a - b c = a % b c = a * b c = a + b
4
a = i128 b = i128Div c = a - b c = a % b c = a * b c = a + b
5
a = i128 b = i128Div c = a - b c = a % b c = a * b c = a + b
i256
a = i256 b = i256Div c = a - b c = a % b c = a * b c = a + b
