Math
Combines two numbers with an arithmetic operation.
Output: number (live result on the card)
Inputs
| Handle | Type | Meaning |
|---|---|---|
| a | number | first operand |
| b | number | second operand |
Unwired inputs use the values typed on the card.
Parameters
| Parameter | Default | Options |
|---|---|---|
| op | add | add, sub, mul, div, min, max, mod |
| a, b | 0, 0 | fallback fields on the card |
Division and modulo by zero return 0 instead of exploding; mod always returns a positive result.
Practical example
Scale a slider into degrees of travel:
- Add a Slider (Min 0 / Max 10) and a Number set to 0.5.
- Add a Math node (op
mul); wire Slider → a, Number → b. - Wire Math → an Orbit node's radius input, and Orbit → an Object Selector targeting a moon object: the slider now sweeps the orbit radius from 0 to 5.
Tip
min/max double as clamps: wire a value into a and type the limit into b.
