`<numberList>`

A list of numbers

<numberList> defines a list of numbers, each like a <number>. Some components that accept a <numberList> as an input include <function>, <repeat>, and <award>.

When creating a <numberList>, separate items by spaces, not commas. The component will default to displaying the list with commas.

Examples

Example: Defining a `<numberList>` and retrieving a value

The <numberList> component stores a list of numbers. Array notation can be used to access an individual element in the list.

Example: A `<numberList>` from multiple `<mathInput/>` components

Combining a number of user-inputs into a <numberList> can be achieved by referencing the named component between the opening and closing tags, separated by spaces.

Example: A `<numberList>` for function evaluation

Here, a <numberList> stores multiple input values to be used in the subsequent code for function evaluation.

Attribute Examples

Attribute Example: unordered

If a <numberList> is defined with the unordered attribute, comparisons (for validation in an <award> or a <boolean> for example) are unordered automatically.

Attribute Example: maxNumber

The maxNumber attribute imposes a limit on the number of numbers that can be stored in the list.

Property Examples

Property Example: numComponents

The numComponents property returns the number of elements stored in a <numberList>.
