How to control the decimal poins for the whole .txt file?
Dear all,
I have a .txt file with n=400 columns, n=440,000 rows. The file looks like below:
-0.0625123454 0.03732424 -0.11293423 ...
0.15651325435 -0.1366346346 -0.28384636 ...
...
I want to change all the numbers in the file with n=3 decimal places. I don't know if it is very simple problem but I don't know how to do it. Thanks a lot for your help.
thanks,
Lin
