| Doc Text: |
A fix to prevent logic errors in various mathematical functions, including exp, exp2, expf, exp2f, pow, sin, tan, and rint, caused by inconsistent results when the functions were used with the non-default rounding mode , creates performance regressions for certain inputs. The performance regressions have been analyzed and the core routines have been optimized to bring performance back to reasonable levels.
