While the number is greater than or equal to 1, divide the number by 2 and increment a counter.

While the number is greater than 0:

If the number is greater than or equal to 1 then subtract 1 from the number and emit 1; otherwise emit 0

Multiply the number by 2. Increment the counter.

continue loop

At some point the counter will be 0. Emit '.' at appropriate time.

The above is not tested and probably has some boundary conditions about what to initialize the counter to, and the best time to emit the '.'
