Answer №1

To change the colon [:] to a dot [.] in JavaScript, you can use the replace method like this:
```
'451.45'.replace(":",".");
```
Once you have the desired string with a dot instead of a colon, you can convert it to a floating point number using parseFloat:
```
parseFloat('451.45');
```
The complete code would look like this:
```
let str = '451:45';
str = str.replace(":", ".");
str = parseFloat(str);
```

Let's consider this:

console.log(+"451:45".replace(':', '.'));

For example:

private convertNumber(n: string): number{
  return +n.replace(':', '.');
}

Answer 5

When working with Angular and TypeScript, you can use the following code snippet:

const str = '451:45';
console.log(Number(str.replace(":", ".")));

If this is within a function, it would look something like this:

convertStringToNumber(inputString: string) {
return Number(inputString.replace(":", "."));
}
