Solution 3

Use string.format or ToString method of float as below

C#

//N2 format for printing 2 decimal places. 
//or use other format as required
textbox3.text=string.Format("{0:N2}",c);
textbox4.text=string.Format("{0:N2}",d);
//or
textbox3.text=c.ToString("N2");
textbox3.text=d.ToString("N2");

Solution 1

You are trying to assign a float type value to a string text box text attribute.
Thus you get the error.

Use the Convert.ToString() method.

C#

textbox3.text=Convert.ToString(c);
textbox4.text=Convert.ToString(d);

Why use convert.tostring(). it can be done by simply calling .tostring on the float type

tostriong() will throw an error in case c is null. So its always a better practice to use Convert.ToString().
