Re: Exponential

[Jim Langston <jlangston@xxxxxxxxxxxxxxxx>]

Actually, there are a number of applications and languages that look at currancy
as integers and process them as such.  Some applications just declare all 
monetary
values as integer and only show the decimal point by dividing by 100 when they
want to show them.  No decimal errors, since you don't have any decimal places.

Quick Basic 7.0 I believe it was (could of been 3.0 or 4.0) introduced a data 
type
of currency.  This was a decimal field with a fixed decimal position of 2.  
This data
type was actually an integer and did all math as an integer, but acted as a 
decimal
field to the programmer.  Another way to get rid of decimal errors.

The same thing could be done in RPG, but I think it would not be quite as easy 
to
convert the integers to decimals with 2 decimal places as easy for output, 
storage
and such.

A data type of currency would be nice, however.

But, then again, that wouldn't help in the least bit with the current problem 
now, would it?
(10 ** 0) would still come out to .99999999999999
