When a number is represented only as a string of bits, with no other symbols, special conventions must be adopted to represent a number that is negative, or one with a radix point indicating a binary fraction.
Another is one's complement notation, in which, when a number is negative, in addition to this being indicated by setting the first bit of the number to a one, the other bits of the number are all inverted.
In these calculations, instead of dealing in numbers which must always be exact in terms of a whole unit, whether that unit is a dollar or a cent, a certain number of digits of precision is sought for a quantity that might be very small or very large.
