| /* 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 above for doubles and |
| the macros are not fully supported by --enable-newlib-hw-fp. |
| |
| __IEEE_BIG_ENDIAN |
| |
| Defined if the float format is big endian. This is mutually exclusive |
| with __IEEE_LITTLE_ENDIAN. |
| |
| __IEEE_LITTLE_ENDIAN |
| |
| Defined if the float format is little endian. This is mutually exclusive |
| with __IEEE_BIG_ENDIAN. |
| |
| Note that one of __IEEE_BIG_ENDIAN or __IEEE_LITTLE_ENDIAN must be specified for a |
| platform or error will occur. |
| |
| __IEEE_BYTES_LITTLE_ENDIAN |
| |
| This flag is used in conjunction with __IEEE_BIG_ENDIAN to describe a situation |
| whereby multiple words of an IEEE floating point are in big endian order, but the |
| words themselves are little endian with respect to the bytes. |
| |
| _DOUBLE_IS_32BITS |
| |
| This is used on platforms that support double by using the 32-bit IEEE |
| float type. |
| |
| _FLOAT_ARG |
| |
| This represents what type a float arg is passed as. It is used when the type is |
| not promoted to double. |
