numerical statistical indicators have lost precision #527

hi masters, when I was doing basic indicator statistics to obtain the max of the NumericComlunProfile type, I found that a long integer number with a length of 19 digits was converted to a Double, and the accuracy was lost. I found that there was a similar feedback before Incorrect Mean calculation #426, his I think the suggestion is more reasonable.
