Math Floor Java Example

This tutorial teaches java math class with examples.

Math floor java example. Because floor is a static method of math you always use it as math floor rather than as a method of a math object you created math is not a constructor. The java lang math floor double a returns the largest closest to positive infinity double value that is less than or equal to the argument and is equal to a mathematical integer. Math floor x parameters x a number. The returned value is of type double.

Java math floor floor accepts double value as an argument and returns the largest integer which is less than or equal to the argument. If the argument is nan or an infinity or positive zero or negative zero. The java lang math floor returns the double value that is less than or equal to the argument and is equal to the nearest mathematical integer. The java floor function is one of the math or mathematical functions available in java math library.

Following is the syntax of floor method. Java math abs round ceil floor min methods with example. Example to show working of java lang math floor method. The java lang math floor is used to find the largest integer value which is less than or equal to the argument and is equal to the mathematical integer of a double value.

This method accepts single parameter asmentioned above and described below. It is the value which is to be tested for math floor. Since the definition of floor function has double datatype as argument you can pass int float or long as arguments. The floor method rounds a number downwards to the nearest integer and returns the result.

If the passed argument is an integer the value will not be rounded. A number representing the largest integer less than or equal to the specified number. The math floor method is used to round off the number passed as a parameter to its nearest integer in downward direction of rounding i e. The java lang math ceil is used to find the smallest integer value that is greater than or equal to the argument or mathematical integer.

Towards the lesser value. Java math class provides useful methods for performing the math s operations like exponential logarithm roots and trigonometric equations too.
