Evaluate Math

What It Does

The Evaluate math node calculates the result of arbitrary mathematical expressions using variables. It lets you create complex formulas combining multiple values without needing multiple math nodes.

Inputs

Name	Description	Type	Required
Expression	Mathematical formula to evaluate	Text	Yes
[Variables]	Custom inputs used in the expression	Number	No

Outputs

Name	Description	Type
Value	The calculated result of the expression	Number
Expression	The expression that was evaluated	Text

How to Use It

1. Drag the Evaluate math node into your graph.

2. Enter a mathematical expression like "a * 2 + b" in the "Expression" input.

3. Add input variables by name (in this case, connect values to inputs "a" and "b").

4. The node will calculate the result based on your formula and connected values.

Tips

• Supports standard operators (+, -, *, /, ^), functions (sin, cos, sqrt), and constants (pi, e).

• Variable names in your expression must match the input names you add to the node.

See Also

• Add (Variadic): For simpler addition of multiple values.

• Multiply (Variadic): For simpler multiplication of multiple values.

Use Cases

• Complex Calculations: Create custom formulas like "width * 0.75 - padding * 2" for layout logic.

• Design Algorithms: Implement specific design calculations such as contrast ratios.

• Responsive Scaling: Create expressions that adjust values based on multiple parameters.
