1、将十六进制转化为十进制的将十六进制转化为十进制的 C C 程序程序 输入：Hex(十六进制数) 输入数据类型：String 输出：HEX_to_DEC(十进制数) 输出数据类型：Long 输入的最大数为 7FFFFFFF,输出的最大数为 2147483647Public Function HEX_to_DEC(ByVal Hex As String) As LongDim i As LongDim B As LongHex = UCase(Hex)For i = 1 To Len(Hex)Select Case Mid(Hex, Len(Hex) - i + 1, 1)Case “0“: B
2、= B + 16 (i - 1) * 0Case “1“: B = B + 16 (i - 1) * 1Case “2“: B = B + 16 (i - 1) * 2Case “3“: B = B + 16 (i - 1) * 3Case “4“: B = B + 16 (i - 1) * 4Case “5“: B = B + 16 (i - 1) * 5Case “6“: B = B + 16 (i - 1) * 6Case “7“: B = B + 16 (i - 1) * 7Case “8“: B = B + 16 (i - 1) * 8Case “9“: B = B + 16 (i
