Fortran requires that INTEGER and REAL be the same size, though
not necessarily use all the bits. The IBM 704, where Fortran started,
stores integers as 16 bits in a 36 bit word.

People doing mixed Fortran and C programming will appreciate
sizeof(int) and sizeof(float) being equal.

Yes, not required, but enough people expect it that hardware
designers would need a good reason not to use all bits zero for 0.0f.
