# Number Cell Editor

Simple number editor that uses the standard HTML number `input`.

The Number Cell Editor allows users to enter numeric values and to modify them using the `↑` `↓` keys.

## Enabling Number Cell Editor

Edit any cell in the grid below to see the Number Cell Editor.

#### Number Editor

```ts
import {
  ClientSideRowModelModule,
  ColDef,
  GridApi,
  GridOptions,
  INumberCellEditorParams,
  ModuleRegistry,
  NumberEditorModule,
  createGrid,
  enableDevValidations,
} from "ag-grid-community";

// Enable extended validations only for development
if (process.env.NODE_ENV !== "production") {
  enableDevValidations();
}

ModuleRegistry.registerModules([ClientSideRowModelModule, NumberEditorModule]);

const columnDefs: ColDef[] = [
  {
    headerName: "Number Editor",
    field: "number",
    cellEditor: "agNumberCellEditor",
    cellEditorParams: {
      min: 0,
      max: 100,
    } as INumberCellEditorParams,
  },
];

const data = Array.from(Array(20).keys()).map((val: any, index: number) => ({
  number: index,
}));

let gridApi: GridApi;

const gridOptions: GridOptions = {
  defaultColDef: {
    width: 200,
    editable: true,
  },
  columnDefs: columnDefs,
  rowData: data,
};

const gridDiv = document.querySelector<HTMLElement>("#myGrid")!;
gridApi = createGrid(gridDiv, gridOptions);
```

[Live example: Number Editor](https://www.ag-grid.com/examples/provided-cell-editors-number/number-editor/typescript)

Enabled with `agNumberCellEditor` and configured with `INumberCellEditorParams`.

```js
columnDefs: [
    {
        cellEditor: 'agNumberCellEditor',
        cellEditorParams: {
            min: 0,
            max: 100
        }
        // ...other props
    }
]
```

## Customisation

### Step and Precision

It is possible to configure the step and precision of the stepping behaviour that increments/decrements the cell value. Edit any cell in the grid below to see a customised stepping behaviour.

#### Number Editor with Changed Precision

```ts
import {
  ClientSideRowModelModule,
  ColDef,
  GridApi,
  GridOptions,
  INumberCellEditorParams,
  ModuleRegistry,
  NumberEditorModule,
  createGrid,
  enableDevValidations,
} from "ag-grid-community";

// Enable extended validations only for development
if (process.env.NODE_ENV !== "production") {
  enableDevValidations();
}

ModuleRegistry.registerModules([ClientSideRowModelModule, NumberEditorModule]);

const columnDefs: ColDef[] = [
  {
    headerName: "Number Editor",
    field: "number",
    cellEditor: "agNumberCellEditor",
    cellEditorParams: {
      precision: 2,
      step: 0.25,
      showStepperButtons: true,
    } as INumberCellEditorParams,
  },
];

const data = Array.from(Array(20).keys()).map((val: any, index: number) => ({
  number: index,
}));

let gridApi: GridApi;

const gridOptions: GridOptions = {
  defaultColDef: {
    width: 200,
    editable: true,
  },
  columnDefs: columnDefs,
  rowData: data,
};

const gridDiv = document.querySelector<HTMLElement>("#myGrid")!;
gridApi = createGrid(gridDiv, gridOptions);
```

[Live example: Number Editor with Changed Precision](https://www.ag-grid.com/examples/provided-cell-editors-number/number-editor-step-and-precision/typescript)

The stepping behaviour to increment/decrement the numeric value can be customised using the properties below:

```js
columnDefs: [
    {
        cellEditor: 'agNumberCellEditor',
        cellEditorParams: {
            precision: 2,
            step: 0.25,
            showStepperButtons: true
        }
        // ...other props
    }
]
```

### Prevent Stepping

The stepping behaviour can be disabled. Edit any cell in the grid below to see this.

#### Number Editor with Prevent Stepping

```ts
import {
  ClientSideRowModelModule,
  ColDef,
  GridApi,
  GridOptions,
  INumberCellEditorParams,
  ModuleRegistry,
  NumberEditorModule,
  createGrid,
  enableDevValidations,
} from "ag-grid-community";

// Enable extended validations only for development
if (process.env.NODE_ENV !== "production") {
  enableDevValidations();
}

ModuleRegistry.registerModules([ClientSideRowModelModule, NumberEditorModule]);

const columnDefs: ColDef[] = [
  {
    headerName: "Number Editor",
    field: "number",
    cellEditor: "agNumberCellEditor",
    cellEditorParams: {
      preventStepping: true,
    } as INumberCellEditorParams,
  },
];

const data = Array.from(Array(20).keys()).map((val: any, index: number) => ({
  number: index,
}));

let gridApi: GridApi;

const gridOptions: GridOptions = {
  defaultColDef: {
    width: 200,
    editable: true,
  },
  columnDefs: columnDefs,
  rowData: data,
};

const gridDiv = document.querySelector<HTMLElement>("#myGrid")!;
gridApi = createGrid(gridDiv, gridOptions);
```

[Live example: Number Editor with Prevent Stepping](https://www.ag-grid.com/examples/provided-cell-editors-number/number-editor-prevent-stepping/typescript)

The stepping behaviour to increment/decrement the numeric value can be disabled as shown below:

```js
columnDefs: [
    {
        cellEditor: 'agNumberCellEditor',
        cellEditorParams: {
            preventStepping: true
        }
        // ...other props
    }
]
```

## API Reference

Properties available on the `INumberCellEditorParams&lt;TData = any, TContext = any&gt;` interface.

| Property | Type | Required | Default | Description |
| --- | --- | --- | --- | --- |
| `min` | `number` |  |  | Min allowed value. |
| `max` | `number` |  |  | Max allowed value. |
| `precision` | `number` |  |  | Number of digits allowed after the decimal point. |
| `step` | `number` |  |  | Size of the value change when stepping up/down, starting from `min` or the initial value if provided. Step is also the difference between valid values. If the user-provided value isn't a multiple of the step value from the starting value, it will be considered invalid. Defaults to any value allowed. |
| `showStepperButtons` | `boolean` |  | `false` | Display stepper buttons in editor. Note: Does not work when `preventStepping` is `true`. |
| `preventStepping` | `boolean` |  | `false` | Set to `true` to prevent key up/down from stepping the field's value. |
