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.
