Java provides two primitive types that can be used for storing decimal numbers. If the argument is nan or an infinity or positive zero or negative zero then the result is the same as the argument. 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. If the argument is nan or an infinity or positive zero or negative zero.

If the argument is integer then the result is integer. Java math class provides useful methods for performing the math s operations like exponential logarithm roots and trigonometric equations too. Foreach decimal value in. You can also use apache common s math library to round double or float to 2 decimal places.

This method has the following variants. 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. The largest integral value less than or equal to d note that the method returns an integral value of type decimal. Double is the type used by default.
