Question

二进制转换成十六进制VB代码

不得用Hex和Oct函数
按位权展开

Answer 1

' 用途：将二进制转化为十六进制
' 输入：Bin(二进制数)
' 输入数据类型：String
' 输出：BIN_to_HEX(十六进制数)
' 输出数据类型：String
' 输入的最大数为2147483647个字符
Public Function BIN_to_HEX(ByVal Bin As String) As String
Dim i As Long
Dim H As String
If Len(Bin) Mod 4 <> 0 Then
Bin = String(4 - Len(Bin) Mod 4, "0") & Bin
End If

For i = 1 To Len(Bin) Step 4
Select Case Mid(Bin, i, 4)
Case "0000": H = H & "0"
Case "0001": H = H & "1"
Case "0010": H = H & "2"
Case "0011": H = H & "3"
Case "0100": H = H & "4"
Case "0101": H = H & "5"
Case "0110": H = H & "6"
Case "0111": H = H & "7"
Case "1000": H = H & "8"
Case "1001": H = H & "9"
Case "1010": H = H & "A"
Case "1011": H = H & "B"
Case "1100": H = H & "C"
Case "1101": H = H & "D"
Case "1110": H = H & "E"
Case "1111": H = H & "F"
End Select
Next i
While Left(H, 1) = "0"
H = Right(H, Len(H) - 1)
Wend
BIN_to_HEX = H
End Function
