For example, in the screenshot below, all reports are formatted in thousands. When summing these amounts (5006 + 3458 + 323), the correct total should be 8787, not 8788. However, the current formula is summing the absolute amounts, leading to an incorrect presentation of data. This is a basic functionality expected by the client, as the system should not have casting or scaling issues in any reports. Which function can I use to address this issue?
