# [Decimal Number Pipe](../../../lib/core/src/lib/pipes/decimal-number.pipe.ts "Defined in decimal-number.pipe.ts")
|
|
|
|
Transforms a number to have a certain amount of digits in its integer part and also in its decimal part.
|
|
|
|
## Basic Usage
|
|
|
|
### Properties
|
|
|
|
| Name | Type | Default value | Description |
|
|
| ---- | ---- | ------------- | ----------- |
|
|
| digitsInfo | [`DecimalNumberModel`](../../../lib/core/src/lib/models/decimal-number.model.ts) | | A format to apply to the date value. [Date Pipe Formats.](https://angular.io/api/common/DatePipe#custom-format-options) |
|
|
| locale | string | 'en-US' | A locale id for the locale format rules to use. |
|
|
|
|
## Details
|
|
|
|
This pipe transforms a given number so it follows the set configuration for the pipe. You can change this configuration by changing the parameters in your `app.config.json`.
|
|
|
|
```json
|
|
"decimalValues": {
|
|
"minIntegerDigits": 1,
|
|
"minFractionDigits": 0,
|
|
"maxFractionDigits": 2
|
|
}
|
|
```
|
|
|
|
You can also overwrite this config by passing a [`DecimalNumberModel`](../../../lib/core/src/lib/models/decimal-number.model.ts) as an argument for this pipe.
|
|
|
|
The number can be also localized so it applies commas and dots in the right place depending on the locale id in use.
|
|
|
|
#### Result
|
|
|
|
```ts
|
|
decimalNumberPipe.transform(1234.567);
|
|
//Returns '1,234.57'
|
|
|
|
decimalNumberPipe.transform(1234.567, digitsConfig, "it");
|
|
//Returns '1.234,57'
|
|
```
|
|
|
|
And now with a different config:
|
|
|
|
```ts
|
|
digitsConfig = {
|
|
minIntegerDigits: 6,
|
|
minFractionDigits: 4,
|
|
maxFractionDigits: 4
|
|
};
|
|
|
|
decimalNumberPipe.transform(1234.567, digitsConfig);
|
|
//Returns '001,234.5670'
|
|
```
|
