Math.abs() Math absolute

	System.out.println(Math.abs(-20));   // 20
	System.out.println(Math.abs(-20.56));// 20.56
	System.out.println(Math.abs(20));    // 20
	System.out.println(Math.abs(20.56)); // 20.56

Practical Uses of Math.abs() in Java

• Distance calculations: In applications like mapping, gaming, or robotics, where the distance between two points is calculated, Math.abs() ensures non-negative values.
• Error handling in measurements: For comparing actual values against expected values (e.g., in scientific experiments or sensor data), Math.abs() is used to compute the absolute error.
• Financial calculations: In accounting or finance-related applications, the absolute value helps to determine the magnitude of profits, losses, or debts without regard to the sign.
• Temperature conversions: When converting temperatures (e.g., between Celsius and Fahrenheit), Math.abs() can be used to ignore the direction of change and focus on the difference in magnitude.
