The default ouput of the exponential digit number is 3 in windows and 2 in
Linux/Unix. How can I reduce the exponential digits output in windows from 3
to 2 as the same in Linux/Unix.
Thanks a lot.

"Note that the number of exponent digits in the scientific notation produced
by %e, %E, %g and %G for numbers with the modulus of the exponent less than
100 is system-dependent: it may be three or less (zero-padded as necessary)
. In other words, 1.23 times ten to the 99th may be either ``1.23e99'' or ``
1.23e099''."
so i suggest you do sprintf and do a regexp replacement.

Thanks. I also notice this paragraph. But is there any way around other than
using regexp replacement?

what is going on here? I could not read your guys' minds. So tell me do you
have a way to specify the exponential digits?
thanks.
