Computer Science Assignment #1: Number Representation

Due Tues., September 7, 2010

All data within a computer is stored in numeric format and the numeric format that is used is binary (base 2). Binary numbers may present a small problem for people, but computers find it much easier.

We have seen that decimal (base 10) values can be represented in binary without any real difficulty and that these binary values can be converted in more easily into hexadecimal (base 16) format.

1. Using the Windows calculator and its Scientific view (Alt-V,S), convert the following values from Decimal into Binary:
   • 45
   • 1248
   • 37.5
   • 12
2. Convert the following binary values to decimal:
   • 1100011
   • 11110001
   • 1100100
   • 10011001
3. Convert the following values from binary to hexadecimal:
   • 1100 0001
   • 0011 1010
   • 1001 0010
   • 1101 0101
4. Convert the following values from hexadecimal to binary:
   • 3D
   • 6F
   • 49
   • BC
