########## docs/sql-manual/sql-functions/aggregate-functions/avg.md: ########## @@ -25,29 +25,97 @@ AVG([DISTINCT] <expr>) ## Return Value Returns the average value of the selected column or expression. If all records in the group are NULL, the function returns NULL. +For decimal type input, return value will be decimal as well, other numric type will return double type. ## Example Review Comment: 像string目前应该只会往double转，不会往int转。 整体各种类型函数入参cast规则应该还比较复杂，可能得专门有一个单独的文档然后link过去，每个函数里去重复描述这个复杂规则不太合适。 -- This is an automated message from the Apache Git Service.
