Operation with real variables and constants

Hello there,

I'd like to define a variable b equal to 0.5/a where a=0.001, so I wrote something like that:

a=0.001;
let 'b=0.5/$a';

but it doesn't work... maybe because the variable a has a real value???

Any help will be appreciated!!!

Try the following

Code:

> a=0.001
> b=0.5/$a
> echo $b
0.5/0.001
> c=`echo 0.5 / $a | bc`
> echo $c
500

char constants vs. hard-coding

This might be a silly question, but I thought I'd ask anyway. If I'm writing in C, isn't it more efficient to, for instance, use constant character variable set to 'A' instead of hard-coding a character 'A'? Since it's only a single character instead of a string, it might not matter much.
