[openbeos] Re: newbie problem

I'm a senior at college majoring in computer science.  I see this problem
all the time when helping first year students with the c++ programs.  There
are internal problems with cout and the use of precision() and some of the
other function that effect the display of numbers which result in it
crashing.  The only suggestion I have is to not call precision() or use my
version of the iostream library when I'm done with it (probably about 90%).
By the way, I rather negative opinions about the implementation of the
iostream   This would be the first time I've seem this happen in BeOS.  Hmm,
well it's also the first time I know someone to call precision() in BeOS.
