Wow. exp() difficulties... [message #9607] Thu, 24 July 1997 00:00

I've encountered a really interesting--though annoying--problem. I'm
trying to use exp(a), where a>88 or so. My calculator can do it...the
program can't. It gives me a "floating underflow" error.

Can anyone give me more information on how to work this out? I haven't
yet figured out long numbers...nor how they differ from floating point.
I don't know if these uncertainties relate, but all of my numbers are
floating point.

Is it just that the language can't handle the numbers? e^89=4.4*10^38;
it's rather large--but is it just that it can't handle the size? Or the
precision? Is it that I need to know more about long numbers?

What *is* a floating underflow?

:) thanks
