math.sub (procNode)

The difference of two values: a minus b, element by element.

The sub operation of the authoring surface, called through the Luau node on proc.fieldc.operators. Operands are numbers, vectors, Columns or Fields. When every operand is a plain number or vector the answer is the plain result, folded where the node cooks; otherwise the answer is a Field: a template over its operands that whatever reads it evaluates in one dispatch together with the chain around it. Nothing dispatches for this node alone. Over numbers and animated values the answer is an animated value: the operation at every time.

Operands of different widths widen to the widest: a number applies to every component, and a shorter vector reads 0 for the components it lacks.

Inputs

• a (Value, default 0). The value subtracted from.
• b (Value, default 0). The value subtracted.

Outputs

• value. The difference.
