Plug the original number range into the list input and the equality test output into the mask input.

If the boolean is changed to false, our result is the number Pi, as defined in the original If statement.
The three Nodes creating the If statement are working identically here.Īgain, the Nodes are working identically. In this image, the boolean is set to true, which means that the result is a string reading: "this is the result if true". Let's go over a brief example on each of these three nodes in action using the conditional "If" statement: There are multiple ways to define an "If" statement in Dynamo: Icon The resulting action of the statement is driven by a boolean value. The "If" statement is a key concept in programming: "If this is true, then that happens, otherwise something else happens. We rarely use booleans to perform calculations because of their limited range. Boolean variables can only store two values referred to as True or False, Yes or No, 1 or 0. Numeric variables can store a whole range of different numbers. After evaluating the test, we will have a Boolean value representing True or False that we can use to control the Program Flow. Logic, or more specifically, Conditional Logic, allows us to specify an action or set of actions based on a test.
