math.isinf(x) Return True if x is a positive or negative infinity, and False otherwise.

to_integral_exact(rounding=None, context=None) Round to the nearest integer, signaling Inexact or Rounded

math.degrees(x) Convert angle x from radians to degrees.

random.sample(population, k) Return a k length list of unique elements chosen from the population sequence or set.

class decimal.Subnormal Exponent was lower than Emin prior to rounding. Occurs

random.setstate(state) state should have been obtained from a previous call to getstate(), and setstate()

copy_sign(other, context=None) Return a copy of the first operand with the sign set to be the same as the sign of the second

math.nan A floating-point “not a number” (NaN) value. Equivalent to the output of float('nan').
