Simple Math(simpleMath)

The Simple Math node (class simpleMath) is a simple calculator that evaluates a mathematical formula supplied as a string. It belongs to the EasyUse/Logic/Math category and is useful for quick arithmetic without adding dedicated math nodes.

Inputs

Write the formula to evaluate in the value field. If you need values from elsewhere in your workflow, connect them to a, b, or c and use those names as variables inside the formula string.

Outputs

The node provides three outputs from the same calculation:

• INT — the result converted to an integer.
• FLOAT — the result converted to a float.
• BOOLEAN — the result interpreted as a boolean value.

All three outputs are produced by the same evaluation, so you can choose the output type that best matches the downstream node.

Usage Notes

Because value is a string, the formula is evaluated at runtime. This makes it possible to build expressions dynamically, for example by connecting a text input or generated string to the formula box.

The optional a, b, and c inputs let you reuse the same formula with different values. For example, with a connected to a number, a formula such as a * 2 would evaluate that value multiplied by two.

The boolean output is useful when you need to treat the numeric result as a true/false condition in logic branches or conditional workflows.
