9. Numeric and Mathematical Modules
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
