Tips for successfully accessing a variable in an Angular Pipe

When displaying output, I need to show a specific number of decimal digits based on the length returned by a stored procedure. The length of these decimal digits can vary, and I only need to focus on the decimal part, not the integer part. To achieve this, I initially used the number pipe with a hard-coded value like this:

{{transaction.Rate | number :'.2-3'}}

This successfully displays the expected value: 713.753 (without the integer part).

However, I have a field in the transaction model called RateDecimal. Instead of hard-coding '3' in the number pipe, I want to pass the value of this field:

{{transaction.Rate | number :'.2-{{transaction.RateDecimal}}'}}

Unfortunately, this throws an error. Can anyone provide guidance on how to achieve this? Your help is greatly appreciated.

Answer №1

Below is an example that demonstrates my solution:

{{transaction.ExchangeRate | number : '.2-' + transaction.CustomerRateDecimal}}

This method works effectively for me since the number pipe requires values inside quotes for the decimal part, hence the concatenation is working well in this case.

Answer №2

Give this a shot: 

{{transaction.Rate | number:transaction.RateDecimal}}
