How can I parse this string "451:45" to a number? What I want to get is "451.45" as number.

Thanks in advance

CodePudding user response：

1. Replace the colon [:] with the dot [.] by using replace method of JS as -

   '451.45'.replace(":", ".");
   

2. Now, we have desired string but as we need number so just parse it into Float by using parseFloat as -

   parseFloat('451.45');
   

   Please find the complete code as -

   let str = '451:45';
   str = str.replace(":", ".");
   str = parseFloat(str);
   
   

Let me know in comments if you need any help further.

Thanks.

so: console.log( "451:45".replace(':', '.')); i.E:

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

If you're using angular and typescrip I use this code

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

I don't know if you have it inside a function in that case would be something like this

stringReplaceToNumber(string: string) {
return Number(string.replace(":", "."))
}
