Constants
Introduction
The following constants can be used in comparison operators and other expressions within a procedure:
| Constant | Description |
| True | Can be used to see if the result of an expression is true |
| False | Can be used to see if the result of an expression is false |
| Pi | The numerical value representing the ratio of a circle's circumference to its diameter (approximately 3.14159265) |
Example
The following example uses the constant True in a comparison.
Figure 1. Using the constant True to check against the current value of a variable.
More information
These constants can be used almost anywhere in a procedure where an expression of the relevant type is required, for example:
Figure 2. Using the constant Pi to calculate the area of a circular arena.
