1. Converting Numbers Between Bases

2. Converting Decimal to Other 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.

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

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

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

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

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