Problem with numbers in Variable

hi all

I think im on the last leg of my poject here. I created a program to take a number and convert it into two "random" points that can be converted back to text later


the problem that im running into is that it works for short numbers (i havent finished the text to number part) so i can get about 7 digits in and then it will crash out



another problem i get is when i output numbers by useing the .tostring() i have been getting Scientific notation for output and i just need straight numbers

anyone know how to turn something like that off?

vb Code:

Random random = new Random();
          float X1, X2, X3, Y1, Y2, Y3;
          //STEP3 MAKE RANDOM PNT1
          X1 = random.Next(2,10000);
          Y1 = random.Next(2,10000);
 
          //STEP2 MAKE PNT2 WITH CONSTANT ( FROM TEXT BOX)
          X2 = Convert.ToInt64(textBox7.Text);
          Y2 = 0;
 
          X3 = 1;
          Y3 = 1;
 
          //STEP4 GET SLOPE FROM PNT1 AND PNT2
          float slope = (Y2 - Y1) / (X2 - X1);
          float t = random.Next(2,10000);
 
          //STEP5 GET RANDOM POINT ALONG LINE MADE PNT1 AND PNT2
          X3 = t + X2;
          Y3 = t * slope + Y2;
 
          //float p = random.Next(1);
          //  X3 = X1+(1-p)*X2;
          //  Y3 = p * Y1 + (1 - p) * 2;
 
          //OUTPUT TO TEXTBOX
          textBox5.Text = t.ToString();
          textBox6.Text = slope.ToString();
 
          textBox1.Text = X1.ToString();
          textBox2.Text = Y1.ToString();
 
          textBox3.Text = X2.ToString();
          textBox4.Text = Y2.ToString();
 
          textBox9.Text = X3.ToString();
          textBox8.Text = Y3.ToString();

What kind of error do you get when it crashes?

To adjust your output to strings, you can use:

Code:

---

.ToString("F12")

---

Where the 12 in this case represents the number of places after the decimal point.

Here is a pretty good description on the tostring method:

http://www.blackwasp.co.uk/CSharpNumericToString.aspx

some times its decimal some times its just a large int.

it sounds like to me it is scientific notation because it is a large decimal. you could use something like

decimal.toInt32(variable);

or

set the number of decimal places.

if you want to get rid of the decimal all together i would use the

decimal.toInt32()
