imaxabs, abs
intmax_t imaxabs(intmax_t i); intmax_t abs(intmax_t i); [C++ only]
The function returns the absolute value of i, |i|.
imaxdiv, div
imaxdiv_t imaxdiv(intmax_t numer, intmax_t denom); imaxdiv_t div(intmax_t numer, intmax_t denom); [C++ only]
The function divides numer by denom and returns both quotient and remainder in the structure result x, if the quotient can be represented. The structure member x.quot is the algebraic quotient truncated toward zero. The structure member x.rem is the remainder, such that numer == x.quot*denom + x.rem.
imaxdiv_t
typedef struct {
intmax_t quot, rem;
} imaxdiv_t;
The type is the structure type returned by the function imaxdiv. The structure contains members that represent the quotient (quot) and remainder (rem) of a signed integer division with operands of type intmax_t. The members shown above can occur in either order.

strtoimax
intmax_t strtoimax(const char *restrict s, char **restrict endptr,
int base);
The function converts the initial characters of the string s to an equivalent value x of type intmax_t. If endptr is not a null pointer, it stores a pointer to the unconverted remainder of the string in *endptr. The function then returns x. strtoimax converts strings exactly as does strtol.
If the string s does not match a valid pattern, the value stored in *endptr is s, and x is zero. If the equivalent value is too large to represent as type intmax_t, strtoimax stores the value of ERANGE in errno and returns either INTMAX_MAX, if x is positive, or INTMAX_MIN, if x is negative.
strtoumax
uintmax_t strtoumax(const char *restrict s, char **restrict endptr,
int base);
The function converts the initial characters of the string s to an equivalent value x of type uintmax_t. If endptr is not a null pointer, it stores a pointer to the unconverted remainder of the string in *endptr. The function then returns x. strtoumax converts strings exactly as does strtoul.
If the string s does not match a valid pattern, the value stored in *endptr is s, and x is zero. If the equivalent value is too large to represent as type uintmax_t, strtoumax stores the value of ERANGE in errno and returns UINTMAX_MAX.
wcstoimax
intmax_t wcstoll(const wchar_t *restrict s, wchar_t **restrict endptr,
int base);
The function converts the initial wide characters of the wide string s to an equivalent value x of type intmax_t. If endptr is not a null pointer, the function stores a pointer to the unconverted remainder of the wide string in *endptr. The function then returns x.
The initial wide characters of the wide string s must match the same pattern as recognized by the function strtol, with the same base argument, where each wide character wc is converted as if by calling wctob(wc)).
If the wide string s matches this pattern, wcstoimax converts strings exactly as does strtol, with the same base argument, for the converted sequence. If the wide string s does not match a valid pattern, the value stored in *endptr is s, and x is zero. If the equivalent value is too large in magnitude to represent as type intmax_t, wcstoimax stores the value of ERANGE in errno and returns either INTMAX_MAX, if x is positive, or INTMAX_MIN, if x is negative.
wcstoumax
uintmax_t wcstoumax(const wchar_t *restrict s,
wchar_t **restrict endptr, int base);
The function converts the initial wide characters of the wide string s to an equivalent value x of type uintmax_t. If endptr is not a null pointer, the function stores a pointer to the unconverted remainder of the wide string in *endptr. The function then returns x.
The initial wide characters of the wide string s must match the same pattern as recognized by the function strtol, with the same base argument, where each wide character wc is converted as if by calling wctob(wc)).
If the wide string s matches this pattern, wcstoumax converts strings exactly as does strtol, with the same base argument, for the converted sequence. If the wide string s does not match a valid pattern, the value stored in *endptr is s, and x is zero. If the equivalent value is too large to represent as type uintmax_t, wcstoimax stores the value of ERANGE in errno and returns UINTMAX_MAX.
