Converting Numbers Between Bases

While the quotient is not zero…  Divide the decimal number by the new base.  Make the remainder the next digit to the left in the answer.  Replace the original dividend with the quotient. Converting Decimal to Other Bases

Converting Decimal to Binary Dim quotient, bDigit As Integer Dim bString As String quotient = ‘number to be converted bDigit = 0 bString = VbNullString

Do While quotient not = 0 bDigit = quotient Mod 2 bString = CStr(bDigit) & bString quotient = quotient \ 2 Loop Converting Decimal to Binary

Converting Binary to Decimal Multiply the bit in each position by the power of 2 in that position, and Sum the products.

Converting Binary to Decimal Dim bLen, number, c As Integer Dim bString As String bString = ‘the binary string to convert bLen = bString.Length-1

Converting Binary to Decimal For c = 0 To bLen number = number + _ Val(bString(c)) * 2 ^ (bLen – c) Next
