Hi:
I am a real beginner of perl. after looking for Internet for serveral
hours, I still can't find the answers for my problem. My question is:
Which function I can use to get 2 digits after point for a variable?
For example, for $j=2.56789, how can I get the very first two digits
after points,ie, I just want to get 2.56.
Thank you very much in advance.
