The function ``convert/binary'' converts a decimal number n to a binary number.  The number may be either positive or negative, and may be either an integer or a floating-point number.  In the case of a floating-point number, an optional third argument determines the total number of digits of precision in the answer (the default being Digits).

The binary number is returned as a base 10 number consisting of the digits 1 and 0 only.
