Under windows, when I need to perform a basic calculations, I use a built-in calculator. Now I would like to find out what is the common way if you only have a shell.
Thanks
From this web page (for csh
and derivatives, since you asked):
% @ x = (354 - 128 + 52 * 5 / 3)
% echo Result is $x
Result is 174
and
% set y = (354 - 128 + 52 / 3)
% echo Result is $y
Result is 354 - 128 + 52 / 3
notice the different results.
Personally, I stick to /bin/sh
and call awk
or something (for maximal portability), or others have exhibited the bash
approach.
