I encountered a situation in my code where I declared a number with a zero decimal like so:
var myNumber: number = 1.0;
When using Angular, it automatically strips off the zero from the value displayed in my form. Converting it to a string is not preferred as it feels like a strange workaround.
Is there a way to instruct Angular to preserve the trailing zero and display it accordingly?
To achieve this, utilize the DecimalPipe
{{myNumber | number : '1.1-1'}}
For detailed explanation of the pipe's parameters, refer to the documentation here
The options for decimal representation are specified by a string in the format: {minIntegerDigits}.{minFractionDigits}-{maxFractionDigits}.
- minIntegerDigits: Represents the minimum number of integer digits before the decimal point. Default is set to 1.
- minFractionDigits: Indicates the minimum number of digits after the decimal point. By default, it is 0.
- maxFractionDigits: Denotes the maximum number of digits after the decimal point. The default value is 3.

To utilize the DecimalPipe, follow these steps:
{{ myNumber | number:'1.1-1' }}
This method indicates:
Ensure there is a minimum of 1 (the 1st one) number preceding the decimal point and
Between 1 (the 2nd one) and 1 (the 3rd one) numbers succeeding the decimal point
Check out the DecimalPipe documentation. Insert this code snippet into your template:
{{ value_expression | number }}
It will show the number exactly as it is defined.
