Before we get into anything worth looking at, let's look at a simple example.
I know that we haven’t looked at arithmetic operators, but I’m sure that you can figure out what the + operator does in the previous example.
The maximum value exceeded the storage capacity for the integer data type, and was automatically converted to a double. A double allows you to store integers and decimal type numbers and has a larger storage capacity than an integer data type.
To make sure that doesn’t happen, look up the maximum value for the data type that you’re setting for that specific cell inside the database, and verify that it can actually support your input.
