Looking at emulator/beam/big.c, it does not appear so.
However, that's something that could be changed without
affecting anything else in Erlang. I note that the Open Solaris
sources include a fast integer multiply, though oddly enough,
not in libmp.
Of course, I was thinking of floating point operations, not large
integer ones. Arguably I _should_ have been thinking of large
I note that the performance of the large integer operations in
Squeak Smalltalk was substantially improved in response to the needs
of cryptography, and suspect that long term, there might be a similar
need for Erlang to have and to be documented as having efficient
large integer arithmetic.
