Fortran: Binary Subtraction (is there a binary type?)

around this issue You need to be a bit clearer about what you mean by 'binary numbers in fortran'. In one sense, not terribly useful, all Fortran numbers are binary, as indeed most numbers in most programming languages are binary once they get onto the computer. Fortran, in the standard at least, does not have the concept of a binary intrinsic data type, it has integers, reals, complex numbers, logicals and characters. Of course, your compiler might implement other types as well, but you don't tell us what that compiler is.

I hope this helps . Take the two's complement of the subtrahend and add it to the minuend. code :
0000 0000
 1111 1111
...
0000 0000
+ 0000 0001

0000 0001

Does that help I need help subtracting with binary using 2's representation and using 5 bits for each number: , 1) 9  7 9  7 = 9 + 7 code :
10111 +
11001 =
110000
00110 +
10110 =
11100

will be helpful for those in need If you really want the output to be 01111 (or 1111, since the leading zero is omitted) you have to make the number positive and then prepend the binary string with the minus sign. Then, when converting it back you have to remove the sign and make the resulting number negative again. code :
Dim BinaryResult As Integer = Convert.ToInt32(TextBox1.Text, 2)  Convert.ToInt32(TextBox2.Text, 2)
If BinaryResult < 0 Then
TextBox3.Text = "" & Convert.ToString(BinaryResult, 2)
Else
TextBox3.Text = Convert.ToString(BinaryResult, 2)
End If
Dim BinaryResult As Integer
If TextBox3.Text.StartsWith("") Then
BinaryResult = Convert.ToInt32(TextBox3.Text.TrimStart(""c), 2)
Else
BinaryResult = Convert.ToInt32(TextBox3.Text, 2)
End If
Private Function BinarySubtract(ByVal a As String, ByVal b As String) As String
Dim BinaryResult As Integer = Convert.ToInt32(a, 2)  Convert.ToInt32(b, 2)
If BinaryResult < 0 Then
Return "" & Convert.ToString(BinaryResult, 2)
Else
Return Convert.ToString(BinaryResult, 2)
End If
End Function
Private Function FromBinary(ByVal s As String) As Integer
If s.StartsWith("") Then
Return Convert.ToInt32(s.TrimStart(""c), 2)
Else
Return Convert.ToInt32(s, 2)
End If
End Function
