OpenBSD reduces to the range [-pi/4,pi/4]: https://github.com/openbsd/src/blob/master/lib/libm/src/s_tan.c According to the man page on i386: http://man.openbsd.org/FreeBSD-11.0/math.3 "Argument reduction is not performed accurately for huge arguments, resulting in large errors for such arguments to cos(), sin(), and tan()." pi/2 is not exactly "huge", but it would be interesting if this occurred on i386. |
