The Integer data type is used for storing integer values. An integer can be positive or negative. This is a 64-bit type. You can use a number from -9223372036854775808 to 9223372036854775807 in an Integer variable.
In Web Application, an Integer field looks as shown in Fig. 1, which features an editing form of a property.
