4b2017adfe Assembly language versions of some of the "float" functions. 1994-08-19 03:56:44 +00:00
jtc
1af6796a8d The fyl2xp1 instruction has a limited range: 
-(1 - (sqrt(2) / 2)) <= x <= sqrt(2) - 1
so we can't use it.

Also, I'm not sure fyl2xp1's extra precision will
matter once the result is converted from extended
real (80 bits) back to double real (64 bits).

9a3e07c4c1 Use BYTE_ORDER == LITTLE_ENDIAN instead of -Dnational to select byte order 
of floating point numbers.

The assumption that a processor's floats use the same order as its integers
is probably unwarranted, but it is better than requiring non-national CPUs
to #define national, as that drags in national-specific code too.
(According to a comment in the code, the national FPU does not do infinity)
