I much prefer the convention of
SInt8, SInt16, SInt32, SInt64, SInt128...
UInt8, UInt16, UInt32, UInt64, UInt128...
SChar8, SChar16, SChar32...
UChar8, UChar16, UChar32...
so that whether the thing is signed or unsigned is explicit and
tightly bound, as it were.

I would think scientific programmers would want similar types
with ability to specify number of bits for mantissas and number
of bits and normalization for exponents, with the compilers
generating the code to work around the floating point functional
unit's characteristics to what is needed. E.g. SFloat128p16n8192
or some such.

The "_t", OTOH, seems affectatiously redundant.
