Zdravím,

Vytváram v C# časomieru a uplynulý čas (minúty) násobím 5 centami, čiže 0,05€.
Problém je v tom , že chcem aby mi v label4 vypísalo nie 175 centov , ale 1,72 €.
kód mam následovný:

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Diagnostics;
using System.Runtime.CompilerServices;
using System.Threading;


namespace Casomiera
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent(); 
         }

        Stopwatch sw = new Stopwatch();
        Stopwatch sw1 = new Stopwatch();
        Stopwatch sw2 = new Stopwatch();
  
        private void button1_Click(object sender, EventArgs e)
        {
            timer1.Start();
            sw.Start();
            button2.Enabled = false;
        }

        private void button3_Click(object sender, EventArgs e)
        {
            timer1.Stop();
            button2.Enabled = true;
            button1.Enabled = false;
        }

        private void button2_Click(object sender, EventArgs e)
        {
            sw.Reset();
            label1.Text = "00:00:00";
            button1.Enabled = true;
 
        }

        private void timer1_Tick(object sender, EventArgs e)
        {
            TimeSpan elapsed = sw.Elapsed;
            label1.Text = String.Format("{0:00}:{1:00}:{2:00}",
            Math.Floor(elapsed.TotalHours), elapsed.Minutes,
            elapsed.Seconds);

            label4.Text = String.Format("{1:00}",
            Math.Floor(elapsed.TotalHours), elapsed.Minutes*5); // násobenie uplynutého času

   
        }
}
