That's a good point. I tried numpy's exp (which uses C at a low level, I think) and found it takes about a fifth as long. I went searching for numpy's implementation, but could only find a C header containing the function prototype.
I only have dmd on my work computer and it probably would be a hassle to get the others working right now.
