Is float.h a POSIX standard ?
I don't know! However, it is in standard C (ISO 9899:1990).
Where FLT_MAX, DBL_MAX, and LDBL_MAX are
present they are defined as, at least, 1E+37 for all sizes
and the implementor of the C compiler is required to
support floating-point to this limit to be conforming.
As an afterthought, I looked at <float.h> for a
"freestanding" implementation of C for an Intel 8051
microprocessor and found the following.
-----
#define FLT_MAX 3.40282e38
#define DBL_MAX FLT_MAX
#define LDBL_MAX FLT_MAX
