Eval

Eval Node

Eval (a.k.a Mathematical Evaluation) node allows you evaluate mathematical and logical expressions easily based on your inputs.

Eval Node Context menu

You can add more inputs via right-clicking on the node and selecting Add Input option from the Node Context Menu, as shown above.

Examples

• If A and B are numbers, you could compute operations like addition, subtraction, multiplication, or more complex functions, such as A + B, sin(A), or sqrt(B)).
• Eval node also supports expressions that involve multiple variables, such as SUM(A, B, C) or AVERAGE(A, B, D, E)
• You can also implement logical expressions using the inputs. For example, using conditions like IF(A > B, A, B) to determine which input is larger.

note

Eval node utilizes Blake-Madden's TinyExpr++. For more details, please visit their repository.
