Is it possible to round uop to next whole # with division in dialogue manager?

-SET &LIMIT = 5;
-SET &NRECS = 3;
-SET &RMAX = (&LIMIT/&NRECS);

or, how do I get a decimal in the remainder to
round it up myself?

Thanks!

Thanks!

Add .5 to your result.

So you would have:

-SET &LIMIT = 5;
-SET &NRECS = 3;
-SET &RMAX = (&LIMIT/&NRECS) + .5;

-SET &RMAX = (&LIMIT/&NRECS) + .5;

would round 11/10 down rather than up.

Dialog Mgr evaluates the right-hand expression in floating-point arithmetic, and then truncates the result to an integer.

Use:

-SET &RMAX = (&LIMIT+(&NRECS-1))/&NRECS ;

[assuming the values will never be negative]

Ah yes, good point Jack. My solution is for regular rounding, where 2.49 becomes 2, and 2.5 becomes 3.

I like your formula for rounding up.
