Introduction to Number Values
In programming, a Number is a numeric value that can be either an integer or a rational number. Numbers are stored in multiple bytes in floating point format, allowing for precise calculations, especially for values with fractional portions. This guide covers the different types of number values, how to declare number variables, and the arithmetic and relational operators that can be used with them.
Key Features:
- Types of Numbers: Understand positive integers, negative integers, floating points, and scientific notation.
- Variable Declaration: Learn how to assign numbers to variables in your code.
- Arithmetic Operations: Explore addition, subtraction, multiplication, and division operations.
- Relational Operations: Use relational operators to compare numbers and return boolean values.
Use Cases:
- Mathematical Calculations: Perform calculations in various applications, from simple arithmetic to complex algorithms.
- Data Representation: Use numbers to represent data in programming, such as scores in games or measurements in scientific applications.
- User Interaction: Display numbers on screens or use them in user inputs for interactive applications.
