You can use like this [sequelize.fn(‘ROUND’, sequelize.fn(‘SUM’, sequelize.col(‘col’)),2), ‘col’] col: is table column name 2: after decimal how much precision you need

Allowing Sequelize to see the dataType of the column and using that in the SUM would be great and sounds like a valid feature request to me. I think it would be nice if you could make a new feature request for that here

Since it’s currently documented that the default fallback is a float and that there is a valid workaround I will close this issue.
