The contents and meaning of the header <cinttypes> are the same as the C standard library header <inttypes.h>, with the following changes:

(1.1)
The header <cinttypes> includes the header <cstdint> instead of <stdint.h>, and
(1.2)
if and only if the type intmax_t designates an extended integer type ([basic.fundamental]), the following function signatures are added:
```
intmax_t abs(intmax_t);
imaxdiv_t div(intmax_t, intmax_t);
```
which shall have the same semantics as the function signatures intmax_t imaxabs(intmax_t) and imaxdiv_t imaxdiv(intmax_t, intmax_t), respectively.
