Notes on arithmetic operations

Please be aware that every operation performed on numerical datatypes is internally stored as a Number. Furthermore, depending on the operation performed it is possible to incur an error related to how intermediate values are stored within Snowflake, for more information please check this post on Snowflake's post on intermediate numbers in Snowflake.
