I am trying to test some multiply function under bash shell, as you can see from the following
$ let 'count = 1.2 * 100'
bash: let: count = 1.2 * 100: syntax error in expression (error token is ".2 * 100")
does not work, seems bash shell does not like ".2"
$ let 'count = 1 * 100'
without .2, accepted,
So my question is, how can i let bash shell do the 1.2 * 100?
Thanks!
