Math Floor Java Int

If the argument is nan or an infinity or positive zero or negative zero then the result is the same as the argument.

Math floor java int.

Towards the lesser value. The java floor function is one of the math or mathematical functions available in java math library. A number representing the largest integer less than or equal to the specified number. This method accepts single parameter asmentioned above and described below.

Floor 返回不大于的最大整数 round 则是 4 舍 5 入的计算 入的时候是到大于它的整数 round 表示 四舍五入 算法为math floor x 0 5 即将原来的数字加上 0 5 后再向下取整 所以 math round 11 5 的结果为 12 math round 11 5 的结果为 11 我们先通过以下实例来看看 java math floor ceil rint 及 round 各个. 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 passed argument is an integer the value will not be rounded. If the argument is nan or an infinity or positive zero or negative zero.

If the argument value is already equal to a mathematical integer then the result is the same as the argument. Math floor x parameters x a number. 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 integer then the result is integer.

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 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 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. 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.

It is the value which is to be tested for math floor.
