What is the usage of the math.ceil function in Java?

In Java, the Math.ceil() method is used to return the smallest integer value that is greater than or equal to the parameter, essentially performing a rounding up operation. This method takes a double or float type parameter and returns a double type result.

For example, Math.ceil(10.3) will return 11.0, and Math.ceil(-10.6) will return -10.0.

It is important to note that the result returned by the Math.ceil() method is always an integer value, even if the parameter itself is a decimal.
