If the internal representation of real numbers is something mantissa&exponent then for a mantissa of 0 the exponent is void/irrelevant/meaningless and to put it to zero is a programmer's free choice. This 'ad libitum' should not affect the result of XPON(0).

Ciao.....Mike

The more I think about it, the more I agree with the answer of the HP-71 as Joe mentioned. The true result should be an error "You attempted to compute the XPON of zero, what in the world do you think you can achieve by that?".

That's the best answer to XPON(0).
