## Usage

Use a `NumberField` to allow a user to enter a number.

## Options

### Number formatting

The NumberField value can be formatted by using the `formatOptions` prop. formatOptions is compatible with the option parameter of [Intl.NumberFormat](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/NumberFormat) and is applied based on the current locale.

<ComponentPreview
  name="core/number-field-format-options"
  preview={`<NumberField
    label="Decimal"
    defaultValue={0}
    formatOptions={{
      signDisplay: "exceptZero",
      minimumFractionDigits: 1,
      maximumFractionDigits: 2,
    }}
  />
  <NumberField
    label="Percentage"
    defaultValue={0.05}
    formatOptions={{
      style: "percent",
    }}
  />
  <NumberField
    label="Currency"
    defaultValue={45}
    formatOptions={{
      style: "currency",
      currency: "EUR",
      currencyDisplay: "code",
      currencySign: "accounting",
    }}
  />
  <NumberField
    label="Unit"
    defaultValue={4}
    formatOptions={{
      style: "unit",
      unit: "inch",
      unitDisplay: "long",
    }}
  />`}
/>

### Size

Use the `size` prop to control the size of the `NumberField`. The default size is `"md"`.

<ComponentPreview
  name="core/number-field-sizes"
  preview={`<NumberField size="sm" />
<NumberField size="md" />
<NumberField size="lg" />`}
/>

### Label

A visual label can be provided for the `NumberField` using the `label` prop or a hidden label using `aria-label` prop.

<ComponentPreview
  name="core/number-field-label"
  preview={`<NumberField label="Width" />
<NumberField aria-label="Width" />`}
/>

### Description

A description can be supplied to a NumberField via the `description` prop. The description is always visible unless the `validationState` is `“invalid”` and an error message is provided.

<ComponentPreview
  name="core/number-field-description"
  preview={`<NumberField label="Width" description="Enter the desired width." />`}
/>

### Contextual help

A `ContextualHelp` element may be placed next to the label to provide additional information or help about a `NumberField`.

<ComponentPreview
  name="core/number-field-contextual-help"
  preview={`<NumberField label="Width" contextualHelp={<ContextualHelp />} />`}
/>

### Error message

An `errorMessage` can be supplied to a `NumberField`, which will be displayed when the `isInvalid` prop is set to `true`.

<ComponentPreview
  name="core/number-field-error-message"
  preview={`<NumberField
    label="Width"
    isInvalid
    errorMessage="Please fill out this field."
  />`}
/>

### Disabled

Use the `isDisabled` prop to disable the NumberField.

<ComponentPreview
  name="core/number-field-disabled"
  preview={`<NumberField isDisabled />`}
/>

### ReadOnly

The `isReadOnly` boolean prop makes the NumberField's text content immutable. Unlike `isDisabled`, the NumberField remains focusable and the contents can still be copied.

<ComponentPreview
  name="core/number-field-read-only"
  preview={`<NumberField isReadOnly />`}
/>

### Required

Use the `isRequired` prop to mark the NumberField as required.
Use the `necessityIndicator` prop to control the visual style of the required state.

<ComponentPreview
  name="core/number-field-required"
  preview={`<NumberField label="Width" isRequired />
<NumberField label="Width" isRequired necessityIndicator="icon" />
<NumberField label="Width" isRequired necessityIndicator="label" />
<NumberField label="Width" necessityIndicator="label" />`}
/>

## Uncontrolled

Use the `defaultValue` prop to set the default input value.

<ComponentPreview
  name="core/number-field-uncontrolled"
  preview={`<NumberField defaultValue={80} />`}
/>

## Controlled

Use the `value` and `onChange` props to control the value of the input.

<ComponentPreview
  name="core/number-field-controlled"
  preview={`const [value, setValue] = React.useState(69);
return <NumberField value={value} onChange={setValue} />;`}
/>

## Composition

If you need to customize things further, you can drop down to the composition level.

<ComponentPreview
  name="core/number-field-composition"
  preview={`<NumberFieldRoot>
    <Label>Quantity</Label>
    <Group className="flex items-center gap-2">
      <Button slot="decrement">
        <MinusIcon />
      </Button>
      <InputRoot>
        <Input />
      </InputRoot>
      <Button slot="increment">
        <PlusIcon />
      </Button>
    </Group>
    <Description>Enter the disired quantity.</Description>
  </NumberFieldRoot>`}
/>
