I committed the patch for expm1 in r76861 (trunk) and r76863 (py3k), with
one small change: instead of using 2 * exp(x/2) * sinh(x/2), expm1 is now
computed using a method due to Kahan that involves only exp and log. This
seems a little safer, and guards against problems on platforms with a
naive implementation of sinh. (I *hope* no such platforms exist, but
suspect that's wishful thinking. :-)
Thanks to Eric Smith for testing the build system changes on Windows. |
