[edit] Mathematical functions and types
[edit] Common mathematical functions
The header <cmath> provides standard C library mathematical functions such as std::fabs, std::sqrt, and std::sin.
[edit] Mathematical special functions (since C++17)
The header <cmath> also provides several mathematical special functions such as std::beta, std::hermite, and std::cyl_bessel_i.
[edit] Mathematical constants (since C++20)
The header <numbers> provides several mathematical constants, such as std::numbers::pi or std::numbers::sqrt2
[edit] Basic linear algebra algorithms (since C++26)
The header <linalg> provides basic linear algebra algorithms which are based on BLAS.
[edit] Data-parallel types (since C++26)
The header <simd> provides portable types for explicitly stating data-parallelism and structuring data for more efficient SIMD access.
