# Java Math abs() method with Examples

The java.lang.Math.abs() returns the absolute value of a given argument.

• If the argument is not negative, the argument is returned.
• If the argument is negative, the negation of the argument is returned.

Syntax :

```public static DataType abs(DataType a)
a : the argument whose absolute value is to be determined
Returns : This method returns the absolute value of the argument.```
1. If the argument is of double or float type:
• If the argument is positive zero or negative zero, the result is positive zero.
• If the argument is infinite, the result is positive infinity.
• If the argument is NaN, the result is NaN.
2. If the argument is of int or long type:
• If the argument is equal to the value of Integer.MIN_VALUE or Long.MIN_VALUE, the most negative
representable int or long value, the result is that same value, which is negative.
