Overview: the different kinds of data stored in a computer
 

 

We will study how signed integer numbers are represented inside a computer next

Review: values
 

Recall that values are intrinsic and does not depend on the representation

Universal representation for values:

 

Negative values
 

A negative value is a value owed and the "owe" concept is universal and culture independent

I will use the red color to depict negative values:

Problem statement

What do we want to do:

 
  • Design a method to represent signed integer (= whole) values

    I.e.: we must represent both the positive values and the negative values (including ZERO)
