Problem with decimals values

[Willian Blyth]

First of all, im developing a program in vb.net, but the code is basically C, if its not allowed, tell me and I deleted the post, im new here!

I have the following problem:
I have 3 textboxes (Txtbox 6, 4 and 3)
I wanna do the following thing:
Textbox 6 = Textbox 3 / (Textbox4 * Textbox4)
I tried the following code:
Static c As Integer
Static d As Integer
c = TextBox4.Text * TextBox4.Text
d = TextBox3.Text
If c >= 0 <= 1000 Then
End If
If d >= 0 <= 1000 Then
End If
TextBox6.Text = d / c
But the problem is that the result is wrong (the program is only considering the entire values, not the values after the comma, for example:
Textbox 6 = 75 / 1,80 * 1,80
Textbox 6 = 75 / 3,24 (the program is considering 3, instead of 3,24)
So the result is (by the program): 25
And the correct result is: 23,1
Any clues what im doing wrong?




Nvm, I found the error and changed the code:


Static c As Decimal
Static d As Decimal


c = TextBox4.Text * TextBox4.Text
d = TextBox3.Text


If c >= 0 <= 1000 Then


End If
If d >= 0 <= 1000 Then


End If




TextBox6.Text = d / c
