I think the answer is no, but somebody can probably say with greater certainty.
Since you mentioned you were doing math, there is a higher possibility
that the things you need are available in 64-bit Tiger. The Unix layer
is 64-bit ready, and I think the Accerlate framework is also. The
Tiger way of doing 64-bit was to build your computation backend into a
separate executable. Then your 32-bit GUI frontend would launch the
executable and you would exchange information through some kind of
IPC. This is another alternative to getting the 64-bit parts you need
on Tiger.
