[vox-tech] Re: totally confused about C promotion

[Peter Jay Salzman]

btw, i *just* found functions like sqrtl and logl in the glibc info
page.  apparently, C99 specifies math functions which take and return
long doubles (as well as floats).  i wish they had man pages...

i think this makes my question less important, but i'm still very
interested in the answer.
