If you need higher performance than what numexpr can give without using 
MKL, you could look at code such as this:

https://github.com/herumi/fmath/blob/master/fmath.hpp#L480

But that means going to C (e.g., by wrapping that function in Cython). 
Pay attention to what range you evaluate the function in though (my eyes 
may deceive me but it seems that the test program only test for 
arguments drawn from the standard Gaussian which is a bit limited..)
