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
33.6666666666
$ echo "scale=3; 101/3" | bc
33.666
$ echo "101/3" | bc -l
33.66666666666666666666
-l auto sets the scale to 20 (as per manpage). Same version of bc.
Thanks
Mark
