bookLogical Types

Let's now turn our attention to logical data types.

For instance, if you evaluate 2 > 1, it will return TRUE because 2 is indeed greater than 1. This principle will be highly relevant in later chapters.

Numbers and strings (text) can also be converted to logical types. Any number except 0 will be converted to TRUE (0 converts to FALSE), and the strings 'F', 'false', 'False', and 'FALSE' will convert to the logical FALSE. The same principle applies for logical TRUE.

When converting logical values to numbers, FALSE becomes 0, and TRUE becomes 1.

  1. Assign the result of the expression 19*54 > 76*13 to the variable logic.
  2. Show the value of the logic variable.
  3. Show the data type of the logic variable.
  4. Convert the logic variable to an integer and show the result.

Avoid using the print() function.
