Bash script: specify bc output number format

Question

Greetings!

I uses bс to make some calculations in my script. For example:

bc
scale=6
1/2
.500000

For further usage

Answer 1

Quick and dirty, since scale only applies to the decimal digits and bc does not seem to have a sprintf-like function:

$ bc
scale = 6
result = 1 / 2
if (0 <= result && result < 1) {
    print "0"
}
print result;
