- There is probably a certain amount of added use to the mathematics
- field.
-
- 64bits allows integer values greater than 4 billion, a limit which
- is easily reached when using exponential and factorial functions.
-
- The extra 32bits might allow an application to stave off the point
- at which arbitrary precision arithmatic has to be added.
