import math
math.e # e
math.pi # pi
math.sqrt(x) # square root (Also commonly seen as x ** 0.5 to obviate importing the math module)
math.log(x) # natural logarithm
math.log10(x) # base 10 logarithm
math.exp(x) # e raised to the power of x
abs(x) # absolute value
math.floor(x) # floor
math.ceil(x) # ceiling
x ** y # exponentiation
pow(x, y[, n]) # exponentiation [, modulo n (useful in certain encryption/decryption algorithms)]
# The math module constants and functions can, of course, be imported directly by:
# from math import e, pi, sqrt, log, log10, exp, floor, ceil
