Numerics library
From cppreference.com
< cpp
The C++ numerics library includes common mathematical functions and types, as well as optimized numeric arrays and support for random number generation.

[edit] Common mathematical functions
The header cmath provides standard C library mathematical functions such as std::fabs, std::sqrt, and std::sin.
[edit] Complex numbers
| Defined in header
<complex> |
|
| a complex number type (class template) |
|
[edit] Numeric arrays
| Defined in header
<valarray> |
|
| numeric arrays and array slices (class template) |
|
[edit] Generic numeric operations
| Defined in header
<numeric> |
|
| (C++11)
|
fills a range with successive increments of the starting value (function template) |
| sums up a range of elements (function template) |
|
| computes the inner product of two ranges of elements (function template) |
|
| computes the differences between adjacent elements in a range (function template) |
|
| computes the partial sum of a range of elements (function template) |

[edit] Pseudo-random number generation
The header random defines pseudo-random number generators and numerical distributions. The header cstdlib also includes C-style random number generation via std::srand and std::rand.
[edit] Compile time rational arithmetic (since C++11)
The header ratio provides types and functions for manipulating and storing compile-time ratios.
[edit] Floating-point environment
The header fenv defines flags and functions related to exceptional floating-point state, such as overflow and division by zero.
