I've used hoc in my scripts to prepare some values which are then used
one for a calculation and second for naming a directory after this
value:
v = `{hoc -e $min+$step'*('$i-1')'}
mkdir $v
However, even for min=0 and step=0.05 (if I remember it right) for
some i I get a value like 6.50000000000something, which is annoying to
correct. That was the reason for my original question.
As proposed I will either add awk to format the result or use awk
exclusively in scripts. Nonetheless, maybe some control over the
format in hoc could be handy...
Thanks
