Following are some examples that illustrate the main implications
of the rules just described.
/* With: Numeric digits 5 */
12+7.00 -> 19.00
1.3-1.07 -> 0.23
1.3-2.07 -> -0.77
1.20*3 -> 3.60
7*3 -> 21
0.9*0.8 -> 0.72
1/3 -> 0.33333
2/3 -> 0.66667
5/2 -> 2.5
1/10 -> 0.1
12/12 -> 1
8.0/2 -> 4
Note: With all the basic operators, the position of the
decimal point in the terms being operated upon is arbitrary. The
operations may be carried out as integer operations with the exponent
being calculated and applied afterward. Therefore, the significant
digits of a result are not in any way dependent on the position of
the decimal point in either of the terms involved in the operation.
