Assignee: Martin Sebor
> std::div(long, long) overload missing from <cstdlib>
> ----------------------------------------------------
>
> Key: STDCXX-323
> URL: https://issues.apache.org/jira/browse/STDCXX-323
> Project: C++ Standard Library
> Issue Type: Bug
> Components: 26. Numerics
> Affects Versions: 4.1.3, 4.1.2
> Environment: all
> Reporter: Martin Sebor
> Assigned To: Martin Sebor

> The well-formed program below fails to compile with 4.1.2. According to c.math, p8, the C++ header <cstdlib> adds an overload of div(long, long) that returns ldiv_t to the C function div(int, int) that returns div_t. Looks like we're missing that overload.
> $ cat t.cpp && make t
> #include <cstdlib>
> int main ()
> {
> std::ldiv_t x = std::div (1L, 1L);
> }
