  Contract: main: void -> int

  Purpose: testing program for the function precision_play
  
  Examples: when this program is run, the following should
            be printed to the screen:
testing precision_play: should see 1.6666666 and 2.7
    formatted to 3 fractional places (but not the 5):
---------------------------------------
1.667
2.700
5

...and now should see 45.222222222 and 13.2
    formatted to 5 fractional places (but not the 2):
---------------------------------------
45.22222
13.20000
2
