Re: Rounding up to nearest 1000

there is also an easy way to use embedded SQL to directly round up/down 

to

nearest 1000. By specifying a negative number in second parameter of the
scalar function round, rounding to 10, 100 and so on can be done.

I think what the SQL engine does is implement the 'generic rounding 
algorithm, so if you don't like the idea of using SQL, you could use an 
RPG procedure.

The rounding algorithm goes something like this:

Let N be the number to round, S be the scale of the rounding (in this 
example S = 1000)
1)  temp = N + S/2
2) result = (temp / S) * S

I think this has to use 'integer division' to work.

This is essentially what the H extender is about - hence the name - 
"(H)alf add".
