The format and function on data of numeric type.
Data of numeric types are data types that are only used to store or operate the numeric data. With these data types, mathematical calculations can be done well even be done at a very high degree of accuracy. Given a numeric data type is only for the number data, preferably in the use of numeric data is not covered or restricted by quotes ("") for the string or sign (##) for date and time.

Internal data is data that is instantly recognizable by the computer because the
data is stored in computer memory (RAM). While the external data is data that is
stored outside the processing device (Floppy disks, hard disks, CD, tape, USB
and others).
Use of operators and functions on data of characters types.
Data of characters type is the type most frequently used data, where these data
types can be used for data Alphanumeric (Alphabetic and Numeric). So with this
data type you can enter data alphabet, numbers, dates, and other data.
Generally it's said that the data have a character data type when the data is
marked with quotes. All alphabets that displayed on the keyboard is a data type
of character. Some functions are reserved for the data of characters type are:
1. &
