Steve Kargl c273267e83 Improve the accuracy from a max ULP of ~2000 to max ULP < 0.79 ... on i386-class hardware for sinl and cosl. The hand-rolled argument reduction have been replaced by e_rem_pio2l() implementations. To preserve history the following commands have been executed: svn cp src/e_rem_pio2.c ld80/e_rem_pio2l.h mv ${HOME}/bde/ld80/e_rem_pio2l.c ld80/e_rem_pio2l.h svn cp src/e_rem_pio2.c ld128/e_rem_pio2l.h mv ${HOME}/bde/ld128/e_rem_pio2l.c ld128/e_rem_pio2l.h The ld80 version has been tested by bde, das, and kargl over the last few years (bde, das) and few months (kargl). An older ld128 version was tested by das. The committed version has only been compiled tested via 'make universe'. Approved by: das (mentor) Obtained from: bde		2011-04-29 23:13:43 +00:00
