MULTIPLICATION (*)

In Arithmetic operators

The MULTIPLICATION operator multiplies two inputs across their combined dimension set. In other words, multiplication uses the union of both inputs’ dimensions.

The result keeps the finer level in each shared dimension and retains dimensions that exist on only one side.

Use this operator for standard multiplication without additional validation handling: 'Volume' * 'Price'.

Parameters

Node1Node referenceRequired

First factor node, specified using the node name in single quotes (e.g.'Volume')

Node2Node referenceRequired

Second factor node, specified using the node name in single quotes (e.g.'Price')

Output shape

Dimensionality

The result uses the combined dimension set (the union of both inputs’ dimensions). Per shared dimension, the finer level is used. Dimensions that exist on only one side are kept as-is.

Level values

Values are matched on shared dimensions. Non-shared dimensions expand the result across matching rows.

Row count

Equal or expanded.

Watch out

Examples

Multiplying nodes with matching dimensions

Input node: 'Node1'

Input node: 'Node2'

Formula: 'Node1' * 'Node2'

Multiplying nodes with some shared dimensions

This example shows how multiplication keeps the finer dimensionality from Node2.

Input node: 'Node1'

Input node: 'Node2'

Formula: 'Node1' * 'Node2'

Multiplying by a scalar

When one input is a scalar value, that value is applied across all rows of the other input.

Input node: 'Node1'

Input node: 'Node2'

Formula: 'Node1' * 'Node2'
