das	0bde705160	Implement exp2l(). There is one version for machines with 80-bit ... long doubles (i386, amd64, ia64) and one for machines with 128-bit long doubles (sparc64). Other platforms use the double version. I've only done runtime testing on i386. Thanks to bde@ for helpful discussions and bugfixes.	2008-01-18 21:42:46 +00:00
das	ac3245defa	Since nan() is supposed to work the same as strtod("nan(...)", NULL), ... my original implementation made both use the same code. Unfortunately, this meant libm depended on a vendor header at compile time and previously- unexposed vendor bits in libc at runtime. Hence, I just wrote my own version of the relevant vendor routine. As it turns out, mine has a factor of 8 fewer of lines of code, and is a bit more readable anyway. The strtod() and *scanf() routines still use vendor code.

das	bb384eba43	Implement and document nan(), nanf(), and nanl(). This commit ... adds two new directories in msun: ld80 and ld128. These are for long double functions specific to the 80-bit long double format used on x86-derived architectures, and the 128-bit format used on sparc64, respectively.	2007-12-16 21:19:28 +00:00
