Basic Java Math Class (10)

Java.lang.Math provides some column static methods for scientific calculations, and the parameters and return value types of the methods are generally double type.

ABS: Absolute value;

Acos,asin,atan,cos,sin,tan;

sqrt: square root;

Pow (double a,double b) a power of B;

LOG: Natural logarithm

Exp:e for base Index

Max (double a,double b): Take maximum value

Min (double a,double b): Minimum value to go

Random (): Returns the number 0.0 to 1.0

Long round (double A): Data A of type double is converted to long (rounded)

Todegrees (double Angrad): radians converted to angles

Toradians (double angdeg): Angle converted to radians

Package mymathclass;

public class Test {

public static void Main (string[] args) {

TODO auto-generated Method Stub

Double A=math.random ();

Double B=math.random ();

System.out.println (Math.sqrt (a*a+b*b));

System.out.println (Math.pow (A, 8));

System.out.println (Math.Round (b));

System.out.println (Math.log (Math.pow (MATH.E, 15));

Double D=60.0,r=math.pi/4;

System.out.println (Math.toradians (d));

System.out.println (Math.todegrees (R));

System.out.println (MATH.E);

System.out.println (Math.PI);

}

}
