## Numeric & Mathematical

### fractions — Rational numbers

**Source code:** `Lib/fractions.py`

### random — Generate pseudo-random numbers

**Source code:** `Lib/random.py`

### statistics — Mathematical statistics functions

**Source code:** `Lib/statistics.py`

### decimal — Decimal fixed point and floating point arithmetic

**Source code:** `Lib/decimal.py`

### cmath — Mathematical functions for complex numbers

This module provides access to mathematical functions for complex numbers. The functions in this module accept integers, floating-point numbers or complex numbers as arguments. They will also accept any Python object that has either a

or a `__complex__()`

method: these methods are used to convert the object to a complex or floating-point number, respectively, and the function is then applied to the result of the conversion.
`__float__()`

### numbers — Numeric abstract base classes

**Source code:** `Lib/numbers.py`

### math — Mathematical functions

This module provides access to the mathematical functions defined by the C standard.
