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 |
