# Standard library header <numeric>

From cppreference.com
< cpp‎ | header

This header is part of the numeric library.

### [edit] Functions

iota (C++11) | fills a range with successive increments of the starting value (function template) [edit]
accumulate | sums up a range of elements (function template) [edit]
inner_product | computes the inner product of two ranges of elements (function template) [edit]
adjacent_difference | computes the differences between adjacent elements in a range (function template) [edit]
partial_sum | computes the partial sum of a range of elements (function template) [edit]

### [edit] Synopsis

            T accumulate(InputIterator first, InputIterator last, T init,
                BinaryOperation binary_op);

        template <class InputIterator1, class InputIterator2, class T>
