Data Representation

Code from lecture

Topics

Data representation

• How is data (numbers for now) represented in memory?
• Positional encoding (Decimal, Binary, Hex,…any base)
• Number conversions
• Big idea:
  • Bits can represent anything!
  • Data is stored in memory using finite number of bits (use this to determine range of values that can be stored in any type)
