syntax

base ** exponent
Math.sqrt(n)
Math.cbrt(n)
Math.pow(base, exp)

example

console.log(2 ** 10);         // 1024
console.log(Math.sqrt(144));  // 12
console.log(Math.cbrt(27));   // 3
console.log(Math.abs(-42));   // 42

Note The ** operator is cleaner than Math.pow() and works with BigInt too: 2n ** 64n.

syntax

import math

example

import math
print(math.ceil(4.2))
print(math.floor(4.8))
print(math.sqrt(144))
print(math.log(100, 10))
print(math.pi)

output

5

12.0
2.0

Note math functions work on ints and floats but not on complex numbers. Use cmath for complex math operations.
