NB: The definition of C/C++ data types fortran_ xxx, and the mapping of Fortran external names to C/C++ external names, is handled by the C/C++ header file. That way, the same function or subroutine name can be used in C, C++, and Fortran code, independent of compiler conventions for mangling of external names in these programming languages.

The range of representable integers is 0 .. (2**p - 1), where p is the number of bits in the significand of a single-precision number.
In IEEE 754 single-precision arithmetic, p = 23, corresponding to the range 0 .. 8388608 (about 0 .. 8.28e+6).
