What is floor function in java.

Java floor method the method floor gives the largest integer that is less than or equal to the argument. The java floor function is one of the math or mathematical functions available in java math library. Similarly ceil is used for nearest upper round off value of a decimal. 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.

If the argument is nan or an infinity or positive zero or negative zero then the result is the same as the argument. The function floor in java is used to get the nearest lower round off value of a decimal as an output. It is the value which is to be tested for math floor. This java math floor function is to return the closest double value which is less than or equal to the specified expression or value and equal to a mathematical integer.

Java math abs round ceil floor min methods with example. This tutorial teaches java math class with examples. If the argument value is already equal to a mathematical integer then the result is the same as the argument. If the argument is integer then the result is integer.

Definition and usage the floor method rounds a number downwards to the nearest integer and returns the result. 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. Java math class provides useful methods for performing the math s operations like exponential logarithm roots and trigonometric equations too. The math floor method returns the smallest integer greater than or equal to the given number.

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.
