Finding the absolute value in Java
Educative Answers TeamIn mathematics, the absolute value of a number is its non-negative value, i.e. the absolute value of -2 is 2.
Absolute value in Java
In order to retrieve the absolute value in Java, we use the abs() function.
Syntax
The general syntax of the abs() function is:
public static datatype abs(datatype number)
Parameters
The function takes as input the argument whose absolute value is to be determined.
Return value
The function returns the absolute value of the argument.
Example
Let’s take a look at how we can find the absolute value using the abs() function!
class HelloWorld {
public static void main( String args[] ) {
/* Converting Integer values */
int x = 123;
int y = -789;
System.out.printf( "Absolute Value of x: %d \n", Math.abs(x) );
System.out.printf( "Absolute Value of y: %d \n", Math.abs(y) );
/* Converting Floating Point values */
float a = 1.23f;
float b = -7.9f;
System.out.printf( "Absolute Value of a: %f \n", Math.abs(a) );
System.out.printf( "Absolute Value of b: %f \n", Math.abs(b) );
}
