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
