Dear Experts,

I want to use bc to do some multiplication and return me a value with number of decimal places defined by myself.

For example:

Code:

echo "scale=10; 1.65*7" | bc

returns me:

Code:

11.55

But what I really want is to have is a result with 10 digits after the point which should look like:

Code:

11.5500000000

But "scale" just doesn't work here. And, if I want to have result without decimal place, for 11.55, it should return me the result like:

Code:

12

Could I achieve these without the help of other command. I know I could pipe the result to awk or another bc (by division for which scale works), but I just interested in if a single bc with some special option can do it simply?

I would greatly appreciate to your kind help!
