/* This file can define macros to choose variations of the IEEE float
|
|
|
|
format:
|
|
|
|
|
|
|
|
_FLT_LARGEST_EXPONENT_IS_NORMAL
|
|
|
|
|
|
|
|
Defined if the float format uses the largest exponent for finite
|
|
|
|
numbers rather than NaN and infinity representations. Such a
|
|
|
|
format cannot represent NaNs or infinities at all, but it's FLT_MAX
|
|
|
|
is twice the IEEE value.
|
|
|
|
|
|
|
|
_FLT_NO_DENORMALS
|
|
|
|
|
|
|
|
Defined if the float format does not support IEEE denormals. Every
|
|
|
|
float with a zero exponent is taken to be a zero representation.
|
|
|
|
|
|
|
|
??? At the moment, there are no equivalent macros for doubles and
|
|
|
|
the macros are not fully supported by --enable-newlib-hw-fp. */
