Constants are entries that have a fixed value. If you ask someone their birthday, they would answer a specific date. People may have different answers, but it is a fixed value for each person.

Data Types

In the example above, the constants are in the columns Price Per Pound and Weight:

  • 1.99, 1.49, 6.99, 5.99
  • 2.4, 1.5, 125, 2
Constants can refer to dollars, dates, percentages, and other items referring to a value that can be used in a calculation.
