Explicit conversions may be performed using the

ptrdiff_t, intptr_t, uintptr_t, and void
Conversions are available for the following scalar types: char, uchar, short, ushort,
int, uint, long, ulong, float, and built-in vector types derived therefrom.
There are datatypes like
Which are covered in section 6.2.3, but not in 18.104.22.168. What is expected of these datatypes?
