How to use the absolute value function (java takes the absolute value function)

php editor Xiaoxin will show you how to use the absolute value function. In Java programming, we often need to perform absolute value operations on numbers, that is, regardless of their sign, only their numerical value. Java provides the abs() method in the Math class to implement this function. Using this method is very simple. You only need to pass in the number whose absolute value you want as a parameter. Whether it is an integer or a floating point number, you can use the abs() method to obtain its absolute value. By learning and mastering this method, we can handle digital operations more flexibly and improve programming efficiency.

Almost everyone knows this.

In Java, if you want to get the absolute value of a number, you can use the abs method in java.lang.Math. This class has 4 overloaded abs methods, which are:

 public static int abs(int a) {        return (a < 0) ? -a : a;    }    public static long abs(long a) {        return (a < 0) ? -a : a;    }    public static float abs(float a) {        return (a <= 0.0F) ? 0.0F - a : a;    }    public static double abs(double a) {        return (a <= 0.0D) ? 0.0D - a : a;    }
