9. Numeric and Mathematical Modules - Python 3.6.15 documentation 编辑
The modules described in this chapter provide numeric and math-related functions and data types. The numbers
module defines an abstract hierarchy of numeric types. The math
and cmath
modules contain various mathematical functions for floating-point and complex numbers. The decimal
module supports exact representations of decimal numbers, using arbitrary precision arithmetic.
The following modules are documented in this chapter:
- 9.1.
numbers
— Numeric abstract base classes - 9.2.
math
— Mathematical functions - 9.3.
cmath
— Mathematical functions for complex numbers - 9.4.
decimal
— Decimal fixed point and floating point arithmetic - 9.5.
fractions
— Rational numbers - 9.6.
random
— Generate pseudo-random numbers - 9.7.
statistics
— Mathematical statistics functions
