K 10 svn:author V 3 bde K 8 svn:date V 27 2005-11-17T03:53:22.000000Z K 7 svn:log V 457 Minor cleanups: s_cosf.c and s_sinf.c: Use a non-bogus magic constant for the threshold of pi/4. It was 2 ulps smaller than pi/4 rounded down, but its value is not critical so it should be the result of natural rounding. s_cosf.c and s_tanf.c: Use a literal 0.0 instead of an unnecessary variable initialized to [(float)]0.0. Let the function prototype convert to 0.0F. Improved wording in some comments. Attempted to improve indentation of comments. END
