Creating a number variable named temp in TypeScript:
temp: number = 0.123;
Is there a way to determine the total count of digits in a number (in this case, it's 3)?

To clarify, you are looking to extract the part of the number after the decimal point.
You can achieve this by converting the number into a string, using the split method with . as the delimiter, and then finding the length of the second item in the resulting array.
const temp = 0.123;
const tempArray = temp.toString().split('.');
const length = tempArray[1].length;
console.log(length);To convert a number to a string and get the decimal length in TypeScript, you can easily achieve it with this code:
this.number.toString().split('.')[1].length
Make sure that this.number is declared as a Number data type.
Try implementing this regular expression: \.\d+
let example = 0.456;
let regexPattern = new RegExp('\\.\\d+', 'g');
console.log(example.toString().match(regexPattern).pop().length - 1);Instead of subscribing to route.queryParams as an Observable, I want it to be a Promise so that I can use async/await for function calls in ngOnInit. However, my attempt at this is not working as expected. The code below does not produce any output: constr ...
