Show decimal numbers with bc

scale defines the number of decimals.

By default, scale is 0 so no decimals are shown.

If you would like to show 2 decimals number, you can set scale to 2.

To do so, type:

scale = 2

before you type your computation.

For example:

$ bc

scale = 2
3850/700

Note: I need to figure how to set default to scale = 2
