Math Op

What is it for?

• Adding two values to offset a position or strength
• Multiplying by a factor to control intensity
• Preparing a value for a threshold calculation or Compare
• Combining parameters into a new value

Overview

The graph's calculator node, supporting arithmetic, min/max, modulo, and power for two numbers. It is the basic building block for numeric wiring that combines parameters into new values.

Usage tips

• Processing waveform outputs is a common use: choose Multiply to change amplitude or Add to shift the center. For simple cases, a single remap may be easier to read.
• Modulo makes values periodic by folding positive or negative inputs into a repeating range from 0 (inclusive) to |B| (exclusive).
• Min / Max guarantee upper or lower bounds. For example, Max(value, 0.1) guarantees a minimum value.
• For three or more terms or a complex expression, consolidating the calculation in expression_float usually makes the graph easier to read.

Related nodes

• math_func — one-input functions such as absolute value, rounding, and trigonometry
• expression_float — evaluate a complex expression in one node
• remap / clamp — dedicated range conversion and limiting nodes
• float_input / int_input — supply constants

Operations

• Add
  • Addition: A + B
  • Example: inputs 2 and 3 produce 5.
• Subtract
  • Subtraction: A - B
  • Example: inputs 5 and 2 produce 3.
• Multiply
  • Multiplication: A * B
  • Example: inputs 4 and 3 produce 12.
• Divide
  • Division: A / B
  • Example: inputs 7 and 2 produce 3.5.
• Min
  • Returns the smaller input.
• Max
  • Returns the larger input.
• Modulo
  • Returns the Euclidean remainder in the range 0 <= result < |B|.
  • Example: inputs -7 and 3 produce 2.
• Power
  • Exponentiation. Returns A to the power of B.
  • Example: inputs 2 and 3 produce 8.

Notes

• Divide and Modulo produce an error when B = 0.
• Add / Subtract / Multiply / Min / Max / Modulo preserve an Int runtime value when both inputs are Int.
• Divide and Power may produce fractional results even when the inputs are integers.
• You cannot connect Bool or Image; this node accepts numbers only.

Examples

1. Add Float Input(0.25) and Float Input(0.5)
   • The result is 0.75.
   • Use this to combine offsets or correction values.
2. Multiply the output of Noise by 0.5 with Math Op(Multiply)
   • Halves the movement range or strength.
3. Use Math Op(Subtract) to calculate current value - threshold, then pass it to Compare
   • This works as preprocessing for a condition.
4. Use Math Op(Max) to set a guaranteed minimum value
   • Useful for preventing values from becoming too small.
