News from the C99 library development front:
The existing assembler version of modfl() has at least two bugs:
y =3D modfl(x,&K)
When x =3D -N, return should be -0 and -N stored in K. =A0 Currently, +0 is=20
returned.
When x =3D Inf, return should be 0. =A0 Currently, NaN is returned.
My new library of long double functions contains a C version of modfl(). Th=
e=20
library will be delivered in the near future. Currently, my attention is=20
fixed on errors of various kinds in my documentation.
I have written several new functions for the long double library including=20
hypotl(). There is a version of hypotl() extant in libc but it isn't workin=
g=20
properly. The new version is fast and very reliable.=20
Also, I'm writing new test-vector generators for the test suite that resides=
=20
in archive djtst203.zip. These generators will produce data for tests of th=
e=20
long double precision functions.
