Let’s Begin
• Discuss the levels of abstraction involved in a computer solution to problem
• Discuss major Numeric Data Types
• Develop expertise in working with various numeric bases
especially base 10, base 2 (binary), and base 16 (hexidecimal)
• Become proficient converting numbers from one base to another
• Become proficient with 2’s complement arithmetic
• Understand round off error, sign extension, and overflow
• Understand representation of floating point numbers
Abstractions:
