  1. Jul 18, 2024 · Some of the examples of non-integers include decimals, fractions, and imaginary numbers. Another example is the number 3.14, which is the value for pi, is a non-integer. Another non-integer is the mathematical constant e, known as Euler’s constant, which is equal to about 2.71.

  2. Aug 4, 2015 · Examples of non-integers include decimals, fractions and imaginary numbers. For example, the number 3.14, which is the value for pi, is a non-integer. Another non-integer is the mathematical constant e, known as Euler’s constant, which is equal to about 2.71. The Golden Ratio, another non-integer mathematical constant, is equal to 1.61.

  3. Discrete variables can only assume specific values that you cannot subdivide. Typically, you count them, and the results are integers. For example, if you work at an animal shelter, you’ll count the number of cats. Discrete data can only take on specific values. For example, you might count 20 cats at the animal shelter.

  4. Irrational numbers extend beyond the realm of fractions and decimals. They cannot be expressed as a fraction or a non-recurring decimal. Classic examples of irrational numbers include pi (𝜋) and the square root of 2 (√2). Irrational numbers possess unique properties and characteristics, such as being non-terminating and non-repeating.

    • Categorical variables. A categorical variable (also called qualitative variable) refers to a characteristic that can’t be quantifiable. Categorical variables can be either nominal or ordinal.
    • Nominal variables. A nominal variable is one that describes a name, label or category without natural order. Sex and type of dwelling are examples of nominal variables.
    • Ordinal variables. An ordinal variable is a variable whose values are defined by an order relation between the different categories. In Table 4.2.2, the variable “behaviour” is ordinal because the category “Excellent” is better than the category “Very good,” which is better than the category “Good,” etc.
    • Numeric variables. A numeric variable (also called quantitative variable) is a quantifiable characteristic whose values are numbers (except numbers which are codes standing up for categories).
  5. Example Problem 1: Identifying Integers and Non-Integers. Identify which numbers in the following list are integers and which are non-integers. − 4, 6.2, 5 2, − 7.0, 10, 8 4. Integers are ...

  7. Oct 11, 2024 · Data Types Data-type in simple terms gives us information about the type of data. Example, integer, character, etc. Data-types in C language are declarations for the variables. Data-types are classified as: Primitive or Built-in data types Some of the examples of primitive data types are as follows Variable named ch refers to the memory address 100
