I am working on an Angular project that includes an input field for users to enter numbers. My goal is to show the number with exactly 3 decimal places if the user submits a whole number. For instance, if the user inputs 6, I want it to be displayed as 6.000 once the user clicks outside of the input field. I am wondering if there is an Angular-specific solution to achieve this?
Thank you
To incorporate the blue event into the input field, follow these steps:
<input (blur)='addDecimals()' [(ngModel)]="usernumber"/>
Implement the following in your component:
public usernumber;
addDecimals() {
this.usernumber.toFixed(3); // this will result in a string
}
While using the decimal Pipe provided by Angular is the recommended approach, guidance on its utilization is not readily available. To make it work, follow these steps:
<input [ngModel]="item| number:'0.3-3' "
(ngModelChange)="item=$event" name="inputField" type="text" />
For more details on how to use the decimal Pipe effectively, refer to this resource.
If you're looking to format decimal numbers in Angular, the DecimalPipe is your friend. Check out the documentation here.
yourValue | number:'0.3-3'
To ensure precision, utilize the parse float method alongside an event trigger like keyup or focusout to execute a function for converting the number.
<input
(focusout)="convert($event.target.value)"
></input>
convert(num){
this.num = parseFloat(num).toFixed(3); //the variable this.num represents the specific number.
}
Include the value in the appropriate HTML section and remember to include number:'0.3-3'
{{valueName | number:'0.3-3'}}
