Re: Round up a number to 4 decimal positions

Or add .00009 and don't round.

Back in the late 70's, on a System/3 Mod 10, The Boss wanted a
multiplication to always be rounded up to the next penny. This was, uh,
several version ago in RPG.

What I settled on (and he agreed to) was rounding to 3 decimal places, add
.009, and truncate. Not perfect math-wise, but it worked.

And that particular calculation, though in free form for many years, Is
Still Done The Same Way. :)

You could add .00005 before rounding.

The rounding opcode/function is doing it correctly now. You're wanting to
do something like a variant of a ceil() function.

Subject: Round up a number to 4 decimal positions

All,
I have a calculation that results in the value of .0141326 that I need to
have rounded up to the fourth decimal position .0142.
What is the best way to do this?
RPGLE Eval(H) results in .0141.
SQL ROUND results in .0141.

Thanks,
