# inttypes.h - [Overview](#section1985275435165627) - [Summary](#section2145262334165627) - [Data Structures](#nested-classes) - [Functions](#func-members) ## **Overview** **Related Modules:** [UTILS](UTILS.md) **Description:** Provides functions and related data structures for conversion between character strings and plural. You can use the functions provided in this file to perform operations related to wide character types during development, for example, performing a division operation, converting a character string to an imax-type parameter, or converting a character string to an umax-type parameter. **Since:** 1.0 **Version:** 1.0 ## **Summary** ## Data Structures

Data Structure Name	Description
imaxdiv_t	Stores the division result.

## Functions

Function	Description
imaxabs (intmax_t j)	intmax_t Calculates the absolute value of an input parameter of the integer type.
imaxdiv (intmax_t numerator, intmax_t denominator)	imaxdiv_t Calculates the quotient and remainder after the division operation is performed on an integer.
strtoimax (const char str, char *endptr, int base)	intmax_t Parses a string to a value of the intmax_t type.
strtoumax (const char str, char *endptr, int base)	uintmax_t Parses a string to a value of the uintmax_t type.
wcstoimax (const wchar_t str, wchar_t *endptr, int base)	intmax_t Parses a string to a value of the intmax_t type.
wcstoumax (const wchar_t str, wchar_t *endptr, int base)	uintmax_t Parses a string to a value of the uintmax_t type.
