I'm not sure what you mean by "immediates", but I don't think so. For the C compiler to do an optimization like we're talking about, you have to give it the entire expression in C for it to compile. From the POV of the C compiler, C-Python never does more than one FP operation at a time when evaluating Python bytecode, and there aren't any intemediate values to store. > Or does Python use its own floating-point math? No, but the C compiler has no way of knowing what the Python expression is. -- Grant -- http://mail.python.org/mailman/listinfo/python-list
