## Playground

This component's contract doesn't list typed props, so the playground shows its documented example.

Documented example `billing-amount-half-up` : type 19.995, 2000 emitted; negative input emits nothing; blank emits undefined.

The render follows the page's theme switch: light, dark or high contrast. Both frameworks render the same example.

The real BillingAmountInput, live

React

Billing amount USD

Vue

Billing amount USD

Events it emits: change. Use either render above, and each event shows here with the framework that sent it.



## Code

The documented example. HTML is the markup the React component renders for it, which @oods/component-styles styles.

**React**

```
import { BillingAmountInput } from '@oods/components-react';
import '@oods/component-styles/css';

export function Example() {
  return (
    <BillingAmountInput
      amount={1999}
      currency="usd"
      minorUnits={100}
      label="Billing amount"
    />
  );
}
```

## Props, slots and events

Contract version 1.1.0. Types are from the React declarations in @oods/components-react.

Props

| Prop | Type | Required | Documented example |
| - | - | - | - |
| `help` | `string \| undefined` | no | |
| `amount` | `number \| undefined` | no | `1999` |
| `currency` | `string \| undefined` | no | `usd` |
| `minorUnits` | `number \| undefined` | no | `100` |
| `label` | `string \| undefined` | no | `Billing amount` |
| `name` | `string \| undefined` | no | |
| `disabled` | `boolean \| undefined` | no | |

### Slots

none

### Events

change

## States

editing, invalid

## Accessibility

- Role

  `textbox`

- How it gets its name

  `label` on `input`

### Keyboard

Keyboard

| Key | What it does |
| - | - |
| `Tab` | Move focus to the named native control |

### Obligations in the contract

- A label names the decimal input
- Currency describes the input
- Invalid input has an associated alert and aria-invalid

Billable amount is an integer number of minor units. Decimal major-unit edits emit number | undefined, rounded half up with decimal arithmetic; zero is valid, blank emits undefined, and negatives or unsafe values retain the draft and emit no update. amountField/currencyField bind runtime amount/currency; minorUnitsParameter resolves to the declared object parameter. Uncontrolled text is retained until amount/minorUnits changes. HTML supplies the same static value and validation semantics; framework components own updates.

## Tokens

The token roles this component reads.

- `billing.amount.text`
- `billing.currency.text`
- `input.border`
- `input.background`
- `input.validation`

## Readiness

The evidence recorded for this component, with its label.

`proven-in-generated-apps`: catalog_list gives this label when generated React and Vue apps in the runtime sweep that ships with this version both use the component. That sweep was measured on the published 0.4.1, not on this version.

## Use your own

You can replace this component with your own React or Vue component. Map it, and generated code imports yours at the exact version you name. A contract report, run in a real browser, lists what your component met, what it didn't, and what wasn't checked.

The `component_map` call, with the parts in angle brackets yours to fill:

```
{
  "action": "create",
  "apply": true,
  "externalSystem": "<your design system>",
  "externalComponent": "<YourBillingAmountInput>",
  "oodsTraits": [
    "Billable"
  ],
  "substitution": {
    "component": "BillingAmountInput",
    "react": {
      "package": "<your-package>/react",
      "version": "<exact version>",
      "export": "<YourBillingAmountInput>"
    },
    "vue": {
      "package": "<your-package>/vue",
      "version": "<exact version>",
      "export": "<YourBillingAmountInput>"
    }
  }
}
```
