I created a rollup summary field "One Off Charge" that will summarize the currency field of the child records. I encountered a problem where on the UI, its showing 10,000.00 but when I tried to get the value by querying it from apex, I got 9999.9999999999999
I check the source (Custom object named "Attribute") of this rollup summary field and i only have 1 child records with 10000 price value.
Then tried to run a query in anonymous. The source value is okay, but the rollup summary is 9999.999999
Anyone can explain why?
