Re: Round up a number to 4 decimal positions

The requirement is to take a currency conversion rate and convert it to a
price value.
The rate in question is 70.758.
The calculation is 1 / Rate (70.758) which yields .0141326.
I need the result to be .0142, not .0141.

When reading the SQL reference, I came across the QUANTIZE function.
When the Set CURRENT DECFLOAT ROUNDING MODE = Round_Up is run followed by
select quantize((1/70.758),.0001) FROM SYSIBM/SYSDUMMY1 in the interactive
sql environment, I get the desired result.
When I put the statements in my program it appears to ignore the Set value.

How can I get this to work in my RPG program?
The embedded SQL is:

Exec SQL
Set CURRENT DECFLOAT ROUNDING MODE = Round_Up;
Exec SQL
Select Quantize(:Work_Price,.0001) Into :Sell_Price
from SysIbm/SysDummy1;

Thanks,

What is the best way to do this?

That is quite a bizarre rounding requirement, but if your SQL has a ceiling
function, it can be done with multiplication, ceiling, and division.

CEIL(myVal * 10000) / 10000
