Program 10: The Not-So-Great-DivideThis is a simple program designed to figure out how many significant digits are used for floating point. The idea is simple: Pick a nice repeating fraction such 1/3 (0.333333), print it, and see how many digits you get.However, the results puzzled this programmer.

Attributes and methods can be added to and dropped from existing object types. In addition, the changes so made can be explicitly
