Which are the basic data types in Excel? (Excel-2007)

Q. Which are the basic data types in Excel?
Ans. In a spreadsheet there are three basic types of data that can be entered:-
·   Labels (text) are descriptive pieces of information such as names, months, or   other identifying statistics, and they usually include alphabetic characters.
·   Values (numbers) are generally raw numbers or dates.
·   Formulas are instructions for Excel to perform calculations.

Data types
Examples
Descriptions
LABELS
Name or Wage or Days
anything that is just text
VALUES
5 or 3.75 or -7.4
any number
FORMULAS
=5+3 or = 8*5+3
math equation

NOTE: ALL formulas MUST begin with an equal sign (=).

Labels are text entries. They do not have a value associated with them. We typically use labels to identify what we are talking about.
In our first example: the labels were
  • computer ledger
  • car loan
  • interest
  • # of payments
  • Monthly Pmt.

Values are entries that have a specific fixed value. If someone asks you how old you are, you would answer with a specific answer. Sure, other people will have different answers, but it is a fixed value for each person.
Examples: the constants are
  • 12,000
  • 9.6%
  • 60

Formulas are entries that follow = sign in a cell. It performs calculations of some type and returns a result, which is displayed in the cell.  Formulas use a variety of operators and worksheet functions to work with values and text.
Examples:
·         =A1+A2+A3
·         =SUM(A1:A3)
·         =25*30
