What does (sin -0.0) evaluate to?
My first guess is that at the C level, sin(-0.0) => 0.0 on your system,
although IEEE 754 and C11 (F.10.1.6) specify that sin(-0.0) => -0.0.
If my guess is incorrect, then please put a breakpoint in
'scm_c_make_polar' and see what's going wrong. Both 'ang' and 's'
should be -0.0, and then it should pass -0.0 as the second argument to
'scm_c_make_rectangular'.
Thanks,
Mark
