Hi Mma experts,
Greetings. The other day i saw another posting with basically the same
question, but haven't seen posted answers yet, so please pardon.
First off, i'm a loyal fan of Mma and WRI, so this is no mean a complain
(how minor it is), but rather, i'm hoping to hear i've been ignorant ...
The idea is that i don't need to save full-accuracy numbers (often
reaching 14-15 decimal places), and instead wanted, say, 2-3 decimal places.
This would cut down the file size by half or so, and even more important,
it makes much better comprehension of the data save. i'm running things that
gave 100-200+ printed pages each run, and need to run a lot (100+ of runs).
Truncated numbers is real helpful, as you can imagine.
i've tried to use NumberForm[ exp, numberLength ], but Print/Write
into files just doesn't evaluate the NumberForm function, making the
printed expressions even harder to read. So, i've been waiting to hear
if someone mentioned this problem/solution.
Thank you for your time and kind help. i'd appreciate it greatly.
