How to reduce C# Unity number?

Question

Unity

private void Update()
{
scoreText.text = score + "$";
}
I've searched the entire Internet, I don't need anything to write 1.21k into this text, for example, so that the variable is shortened!

Answer 1

If the number is more than a million, then divide by a million and add the letter "M", otherwise if it's more than a thousand ... etc.

Answer 2

public string IntReduse(int score){
   if (score >= 1000 && < 1000000)
      return (score/1000).ToString("0.00") + "K";
   else if (score >= 1000000)
      return (score/1000000).ToString("0.00") + "M";
   else 
      return score;
}

Etc.

Answer 3

Start simple: put the dollar sign in front of the number.
