, NUMBER TYPES

Format Description
General The default number format that Excel applies when you type a
number. For the most part, numbers that are formatted with
the General format are displayed just the way you type them.
However, if the cell is not wide enough to show the entire number,
the General format rounds the numbers with decimals.
The General number format also uses scientific (exponential)
notation for large numbers (12 or more digits).

Number Used for the general display of numbers. You can specify the
number of decimal places that you want to use, whether you want
to use a thousands separator, and how you want to display negative
numbers.

Currency Used for general monetary values and displays the default currency
symbol with numbers. You can specify the number of decimal places
that you want to use, whether you want to use a thousands
separator, and how you want to display negative numbers.

Accounting Also used for monetary values, but it aligns the currency symbols
and decimal points of numbers in a column.

Date Displays date and time serial numbers as date values, according to
the type and locale (location) that you specify. Date formats that
begin with an asterisk (*) respond to changes in regional date and
time settings that are specified in Control Panel. Formats without an
asterisk are not affected by Control Panel settings.

Time Displays date and time serial numbers as time values, according to
the type and locale (location) that you specify. Time formats that
begin with an asterisk (*) respond to changes in regional date and
time settings that are specified in Control Panel. Formats without an
asterisk are not affected by Control Panel settings.

Percentage Multiplies the cell value by 100 and displays the result with a percent
(%) symbol. You can specify the number of decimal places that you
want to use.

Fraction Displays a number as a fraction, according to the type of fraction
that you specify.

Scientific Displays a number in exponential notation, replacing part of the
number with E+n, where E (which stands for Exponent) multiplies the
preceding number by 10 to the nth power. For example, a 2-
decimal Scientific format displays 12345678901 as 1.23E+10, which is 1.23
times 10 to the 10th power. You can specify the number of decimal
places that you want to use.

Text Treats the content of a cell as text and displays the content
