Well, it normally adds binary zeros onto the end of the
binary representation.

A binary fraction converted to decimal has the same number of
digits after the decimal point as the binary fraction
has after the binary point.   In precision, a decimal digit
is worth about 3.32 bits.   Conversion digits isn't a
bad name for them.
