We don't yet have debugger and shell support for Python 3.2.  The issue 
here is that the bytecode version number often still changes in alphas 
and betas and thus it's a problem to support them.  You could recompile 
the debugger support yourself and it might work, but we've not even 
tested this yet with Python 3.2 as far as I know.

It looks like these functions are written in C in Modules/mathmodule.c 
but they are pretty simple so maybe a solution would be just to copy the 
implementation, make it into Python, and use it with Python 3.1 or 
earlier.  They would only be performance critical if called a lot of 
times, or at least it looks like each call does not loop very many times.
