math.asin (procNode)

The angle whose sine is the value, in radians, from -pi / 2 to pi / 2, element by element. A value past -1 or 1 reads as the nearest of the two.

The asin 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.

Inputs

• a (Value, default 0). The sine.

Outputs

• value. The angle in radians.
