Abstract
The numbers in the programs that we have considered so far have been unsigned (positive) whole numbers having pictures such as 99 and 999. In this chapter we first consider numbers which have a fractional part (i.e. a decimal point in the number) and then consider signed numbers — numbers which may be negative or positive (i.e. have a − sign or a + sign in front of the number).
