imaxdiv man page


This manual page is part of the POSIX Programmer's Manual. The Linux implementation of this interface may differ (consult the corresponding Linux manual page for details of Linux behavior), or the interface may not be implemented on Linux.

imaxdiv — return quotient and remainder


#include <inttypes.h>

imaxdiv_t imaxdiv(intmax_t numer, intmax_t denom);


The functionality described on this reference page is aligned with the ISO C standard. Any conflict between the requirements described here and the ISO C standard is unintentional. This volume of POSIX.1‐2008 defers to the ISO C standard.

The imaxdiv() function shall compute numer / denom and numer % denom in a single operation.

Return Value

The imaxdiv() function shall return a structure of type imaxdiv_t, comprising both the quotient and the remainder. The structure shall contain (in either order) the members quot (the quotient) and rem (the remainder), each of which has type intmax_t.

If either part of the result cannot be represented, the behavior is undefined.


No errors are defined.
