Data types

Data types

1. Integer

   • The Integer data type is used to store whole numbers, including negative numbers. Integer data can be treated mathematically and it is possible to perform a range of mathematical operations on this type of data using the operators +, -, *, /, = and ^ as well as others. Values such as -43, 92, 0, 18 are all examples of suitable data for an integer variable.

2. Real or float

   • Real data types are used when floating point numbers need to be stored. Like the integer data type, it is possible to perform a range of mathematical operations on this type of data. Values such as 1.54, 7.77, 8.2657 can be stored as real variables. It is possible to define how many values are held after the decimal point, allowing for the desired level of accuracy for specific tasks.

3. Boolean

   • The Boolean data type is used to store True or False values. This data type can only hold two states. Programming languages allow for the use of the terms True and False but the data will be held as a 1 (True) or 0 (False).

4. Character

   • A single letter, number, symbol.

5. String

   • Used to represent text, it is a collection of characters
