power(x, y, modulo=None) Return x to the power of y, reduced modulo modulo if given. With two arguments, compute x**y. If x is negative then y must be integral. The result will be inexact unless y is integral and the result is finite and can be expressed exactly in ‘precision’ digits. The rounding mode of the context is used. Results are always correctly-rounded in the Python version. Changed in version 3.3: The C module computes power() in terms of the correctly-rounded exp() and ln() func

plus(x) Plus corresponds to the unary prefix plus operator in Python. This operation applies the context precision and rounding, so it is not an identity operation.

number_class(x) Returns an indication of the class of x.

normalize(x) Reduces x to its simplest form.

next_toward(x, y) Returns the number closest to x, in direction towards y.

next_plus(x) Returns the smallest representable number larger than x.

next_minus(x) Returns the largest representable number smaller than x.

multiply(x, y) Return the product of x and y.

min_mag(x, y) Compares the values numerically with their sign ignored.

minus(x) Minus corresponds to the unary prefix minus operator in Python.
