Keep any value in range

Introduction #

The Propeller native SPIN and SPIN2 languages include many efficient instructions to solve common programming tasks.

For example, how to keep a value between a certain range of allowed values?

Here's an example using just one line of code!

Code Snippet #

value := 1 #> value <# 4               ' Limit value range from 1 to 4 	
				

The result of the operation follows these rules:

• If value is less than 1, then value = 1
• If value is greater than 4, then value = 4
• If value is 1, 2, 3 or 4, then value will remain unchanged.
