Bug#153022: sin() and cos() also have poor accuracy at points

[Jason McCarty <bclg@iup.edu>]

This is perhaps off-topic, but I thought I'd append it to this bug. On
x86, sin() has poor precision near PI, and cos() has poor precision near
PI/2, according to http://www.naturalbridge.com/floatingpoint/intelfp.html
This would appear to be a hardware bug rather than one in libc though.
