# Find absolute value in Java

Absolute value is the value which is got by neglecting the signs of the existing value. For eg the absolute value of -12 is 12.

abs(double d), abs(float f), abs(int i) and abs(long l) methods of Math class can be used to find absolute of a value in Java.

The class belongs to java.lang package. The methods are static, so it can be called directly using class name without creating object.

## abs(double d)

abs(double d) method can be used to get absolute of a double value.

static double abs(double d) method since it is static we can call directly using class name Math. e.g Math.abs(-20.9999999999).

### Example

class MathTest{

public static void main(String args[]){

double d=-12.9999999;

double dtoabs=Math.abs(d);

System.out.println("Absolute value of variable d is "+dtoabs);

}

}

### Output

Absolute value of variable d is 12.9999999

## abs(float f)

abs(float f) method can be used to get absolute of a float value.

static float abs(float f) method since it is static we can call directly using class name Math. e.g Math.abs(-150.6).

### Example

class MathTest{

public static void main(String args[]){

float fl=-12.9999;

float ftoabs=Math.abs(f1);

System.out.println("Absolute value of variable f is "+ftoabs);

}

}

### Output

Absolute value of variable f is 12.9999

## abs(int i)

abs(int i) method can be used to get absolute of a int value.

static int abs(int i) method since it is static we can call directly using class name Math. e.g Math.abs(-2).

### Example

class MathTest{

public static void main(String args[]){

int i=-12;

int itoabs=Math.abs(i);

System.out.println("Absolute value of variable i is "+itoabs);

}

}

### Output

Absolute value of variable i is 12

## abs(long l1)

abs(long l1) method can be used to get absolute of a long value.

static long abs(long l1) method since it is static we can call directly using class name Math. e.g Math.abs(-200000000).

### Example

class MathTest{

public static void main(String args[]){

long ll=-20000000000;

int ltoabs=Math.abs(ll);

System.out.println("Absolute value of variable ll is "+ltoabs);

}

}

### Output

Absolute value of variable ll is 20000000000
