Description
glibc fails to respect rounding modes set through `` when evaluating transcendental functions.
This means that this approach, while it works for primitive operations like, addition and multiplication, fail when applied to exp, log, cos, sin, etc.
In particular, some errors like sin 1 when rounding up, are quite ridiculously far off.
