This chapter discusses how to control the apperance of a number when it is converted into characters. This is usually done when a number is output to the monitor or to a file. For example, instead of
value = 13.333333333333334
you can ask for only two places right of the decimal point:
value = 13.34
There is much more to formatting numbers than this chapter discusses. Sometime in the future you may wish to study the detailed documentation.
