IEEE754 fp

[Ravishankar S]

Hello C-Experts,

Is there any predefined constant in Std C which specifed that the
implementation uses the IEEE754
standard for floating point operation ?

__STDC_IEC_559__
But note that there are many implementations which partially conform to
the Annex F, and do not define __STDC_IEC_559__, even if, for example,
floating point numbers are stored with the IEEE754 representation.
