INFINITY

#define INFINITY <float rvalue> [added with C99]

The macro yields a float value that represents positive infinity.
isfinite

#define isfinite(x) <int rvalue> [added with C99, bool functions in C++]

Sure. I'm not sure what the significance is to this thread though.

Incorrect. THe specification of floating point is in terms of sign*mantissa*10^exponent. The individual fields in the floating point variable (mantissa and exponent) will be represented in binary, but that doesn't mean floating point formats are specified as you have stated here.
