In computer science, Boolean data has two main values: TRUE or FALSE.
Sometimes, Boolean values are represented by the numbers " 1 " and " 0 ", with TRUE equaling 1 and FALSE equaling 0.
In Excel, Boolean values are used by the program's Logic Functions, such as IF, AND, and OR.
For example, the IF function evaluates a mathematical statement to see if it is TRUE or FALSE.
If a TRUE value is returned, the function will perform one action.
If a FALSE value is returned, the function will perform a different action.
