Ada decimal types

["REH" <spamjunk@stny.rr.com>]

We are in the process of converting our software from '83 to '95, and
have the opportunity to port over to some of the new features 95
provides.  We have a 64-bit mission time that is represented as a
record of two 32-bit values (one for seconds and one for microseconds).
 Is it advantagous to use:

type Mission_Time_Type is delta 1.0e-6 digits 16 range 0.0 .. (2.0**32)
- 1.0;

instead?  I was thinking this would make the math easier and less
"klunky."  Are there any ramifications of using decimal types that I
should be aware of?  I can't find any info.  that goes in depth on the
subject.

Thanks,
