Integer virtual sequences
Factor handbook » The language » Numbers » Arithmetic » Bitwise arithmetic

The math.bits vocabulary implements words that represent a positive integer as a virtual sequence of bits in order of ascending significance, e.g. { f f f t } is 8.
bits
( number length -- bits )
make-bits ( number -- bits )
bits>number ( seq -- number )

If you need binary digits instead of boolean, then you can use these:

binary-bits

( number length -- binary-bits )
make-binary-bits ( number -- binary-bits )
