Rounding 235000 to 235?

Question

Hello everyone, I'm looking for some assistance today with an idea I had, So in my game you have currency which you can view in the inventory. What I would like to achieve is say the player has 235145 Gold, I would like to convert that into say 235k.

Does anyone know a way to round to the first number or first 3 numbers?? and this wouldn't be to convert the whole number but only while displaying it with GUI.label.

Example:

100000 = 100k, 1000000 = 1m, 10000000 = 10m, 1000000000 = 1b,

Any assistance would be appreciated :) thank you very much!

Google and Stack Overflow know everything.

In this case it was the top search result on Google for "c# string format million"

Heres a nifty extension method I wrote:

   public static class MathExtensions
   { 
       public enum RoundingMode
       {
           Nearest,
           Up,
           Down
       }
       public static float Round(float value, int digits = 0, RoundingMode mode = RoundingMode.Nearest)
           {
             float rounder = digits == 0 ? 1 : (float)Math.Pow(10, (float)digits);
             
             switch(mode)
             {
                 case RoundingMode.Up:
                     return  (float) (Math.Ceiling(value/rounder) ) * rounder;
                     
                 case RoundingMode.Down:
                     return (float) (Math.Floor(value/rounder) ) * rounder;
                     
                 default:
                     return (float) (Math.Round(value/rounder) ) * rounder;
             }
           }
 
   }
