sub tag

Transient logic tag

Subtracts values and generates the result.

Sample usage

• <sub 10,3> generates 7.
• <sub 10,3,2> generates 5 (each value after the first is subtracted in turn).
• <sub 10,1,2 with=1> generates 9, 0, 1.
• <sub 5 with=1,2> generates 4, 3.

Fields

Primary field

Vector field

A list of one or more numerical values.

Secondary fields

• with: (vector field, optional) a value or list of values for distributive or pairwise calculation. See with field.

Behaviour

Without a with field, the second and later values are subtracted from the first, and one result is generated. With a with field, the tag works element by element, in the same way as add.

• null items are left out: <sub 10,null,3> generates 7. If every value is null, the result is null.
• Text, true and false generate invalid.
