Java Math Class

Java Math Class:

We can use the Eclipse IDE for this example. If you do not know about it then follow this link- How to Install Eclipse For Java and create a program in it.

In Java, all mathematical functions are the static methods of the Math class in the package java.lang. Important mathematical methods of the Java math class are given below in the table.

Math.abs()Returns an absolute value of the given numeric data by ignoring the sign.
Math.min()Returns the smaller value.
Math.max()Returns the larger value.
Math.sqrt()Returns the square root of the value.
Math.cbrt()Returns the cube root of the value.
Math.pow()Returns the value of the first argument raised to the power of the second argument.
Math.ceil()Returns the smallest integer value greater than the given argument.
Math.floor()Returns the largest integer value smaller than the given argument.
Math.round()Returns the nearest integer value.
Math.random()Return any value between 0 and 1.
Math.log()Returns the natural logarithm of the value.
Math.rint()Converts double value to integral value in double format.
Math.hypot()Precision calculation of the sqrt() of x2+y2
