Math Floor Java Int

The java floor function is one of the math or mathematical functions available in java math library.

Math floor java int.

If the argument is nan or an infinity or positive zero or negative zero. If the passed argument is an integer the value will not be rounded. 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. It is the value which is to be tested for math floor.

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. Math floor x parameters x a number. 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. Public static double. Towards the lesser value. A number representing the largest integer less than or equal to the specified number.

If the argument value is already equal to a mathematical integer then the result is the same as the argument. 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. Java floor method the method floor gives the largest integer that is less than or equal to the argument.

The floor method rounds a number downwards to the nearest integer and returns the result.
