* math: sin cos cleanupSzabolcs Nagy2013-05-181-9/+11
| | | | | | | | * use unsigned arithmetics * use unsigned to store arg reduction quotient (so n&3 is understood) * remove z=0.0 variables, use literal 0 * raise underflow and inexact exceptions properly when x is small * fix spurious underflow in tanl
* fix missing prototype and simplify sincosl on ld64 archsRich Felker2012-07-021-4/+2
