# <numeric> library in C++ STL

Common mathematical functions

• std::fabs: This function returns the absolute value.
• std::sqrt: This function returns the square root
• std::sin: This function returns the sine measured in radians.

Special mathematical functions

• std::beta: This function evaluates the (complete) Beta integral with given parameters
• std::hermite: This function Returns the value of the Hermite Polynomial of order n at point x
• std::cyl_bessel_i: This function returns value of the regular modified cylindrical Bessel function.

Complex number arithmetic

• complex: a complex number class, defined in header (class template)

Numeric arrays

• valarray : numeric arrays, array masks and array slices (class template)

Factor operations(Defined in header )

• gcd: constexpr function template returning the greatest common divisor of two integers. (function template)
• lcm: constexpr function template returning the least common multiple of two integers (function template)

Numeric operations(Defined in header )

• iota: fills a range with successive increments of the starting value (function template)
• accumulate: sums up a range of elements (function template)
• reduce: similar to std::accumulate, except out of order (function template)
• transform_reduce: applies a functor, then reduces out of order (function template)
• inner_product: computes the inner product of two ranges of elements .(function template)
• adjacent_difference: computes the differences between adjacent elements in a range (function template)
• partial_sum: computes the partial sum of a range of elements (function template)
• inclusive_scan: similar to std::partial_sum, includes the ith input element in the ith sum (function template)
• exclusive_scan: similar to std::partial_sum, excludes the ith input element from the ith sum (function template)
• transform_inclusive_scan: applies a functor, then calculates inclusive scan (function template)
• transform_exclusive_scan: applies a functor, then calculates exclusive scan (function template)
