nctions math.ceil(x) Return the ceiling of x, the smallest integer greater than or equal to x. If x is not a float, delegates to x.__ceil__(), which should return an Integral value. math.comb(n, k) Return the number of ways to choose k items from n i

gn of y. On platforms that support signed zeros, copysign(1.0, -0.0) returns -1.0. math.fabs(x) Return the absolute value of x. math.factorial(x) Return x factorial as an integer. Raises ValueError if x is not integral or is negative. math.floor(x) R

xpression x % y may not return the same result. The intent of the C standard is that fmod(x, y) be exactly (mathematically; to infinite precision) equal to x - n*y for some integer n such that the result has the same sign as x and magnitude less than

abs(y). Python's x % y returns a result with the sign of y instead, and may not be exactly computable for float arguments. For example, fmod(-1e-100, 1e100) is -1e-100, but the result of Python's -1e-100 % 1e100 is 1e100-1e-100, which cannot be repr

esented exactly as a float, and rounds to the surprising 1e100. For this reason, function fmod() is generally preferred when working with floats, while Python's x % y is preferred when working with integers. math.frexp(x) Return the mantissa and expo

nent of x as the pair (m, e). m is a float and e is an integer such that x == m * 2**e exactly. If x is zero, returns (0.0, 0), otherwise 0.5 <= abs(m) < 1. This is used to "pick apart" the internal representation of a float in a portable way. math.f
