Hi,
I'm just trying to do some quick calculations using bc, but the version
installed through portage truncates on multiplication/division. It didn't
used to do this 2 years ago when I was taking number theory, and there are
no USE flags available for sys-devel/bc to change this. From the manpage:
$ bc
bc 1.06

Hi,
I have always understood bc has always truncated (or at least through
my general usage) whenever I have needed it to grow the decimal
precision I use the scale= option:
$ echo 101/3 | bc
33
$ echo scale=10; 101/3 | bc
33.66
$ echo scale=3; 101/3 | bc
33.666
$ echo 101/3 | bc -l
33.
-l auto sets the scale to 20 (as per manpage). Same version of bc.
Thanks
Mark
