Numerics library
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.
Mathematical special functionsThe header |
(since C++17) |
[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] Numeric algorithms
| Defined in header
<numeric> | |
| (C++17) |
constexpr function template returning the greatest common divisor of two integers (function template) |
| (C++17) |
constexpr function template returning the least common multiple of two integers (function 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) | |
| (C++17) |
similar to std::accumulate, except out of order (function template) |
| (C++17) |
applies a functor, then reduces out of order (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) | |
| (C++17) |
similar to std::partial_sum, includes the ith input element in the ith sum (function template) |
| (C++17) |
similar to std::partial_sum, excludes the ith input element from the ith sum (function template) |
| (C++17) |
applies a functor, then calculates inclusive scan (function template) |
| (C++17) |
applies a functor, then calculates exclusive scan (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(since C++11)
The header cfenv defines flags and functions related to exceptional floating-point state, such as overflow and division by zero.
