[Bug c/23122] New: Problems with functions sinl and cosl

["agdu at terra dot com dot br" <gcc-bugzilla at gcc dot gnu dot org>]

I was developing a program who uses these functions, but this function return 
to me diferent values in module for complementary angles for example: 
sinl(0) is 0.0 but the function return to me 
0.00000000000000000015586265845163368456161...
My program needs precision in the values retuned from the functions, because 
I'm working with Long Double values and I need to recovery full value, but I'm 
not receiveing right results. If someone know to solve this send to me a 
message.

Thanks your atttention.
