Math floor java int.
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 value is already equal to a mathematical integer then the result is the same as the argument.
The java floor function is one of the math or mathematical functions available in java math library.
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.
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 integer then the result is integer.
Java floor method the method floor gives the largest integer that is less than or equal to the argument.
This method accepts single parameter asmentioned above and described below.
Towards the lesser value.
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.
Public static double.
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.
If the argument is nan or an infinity or positive zero or negative zero.
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 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.
Math floor x parameters x a number.
