Formatting binary values in Scala

Question

Does Scala have a built in formatter for binary data?

For example to print out: 00000011 for the Int value 3.

Writing one won\'t be difficult - just curious

Answer 1

I usually use to prepend zeroes of the wanted length -1 and then just chop the rightmost characters:

"0000000" + 3.toBinaryString takeRight 8

This works fine for negative values as well.
