The method floor gives the largest integer that is less than or equal to the argument.
Floor rounding java.
Otherwise behaves as for roundingmode down.
This method is used to return the closest long to the argument with ties rounding to positive infinity.
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.
Rounding mode to round towards nearest neighbor unless both neighbors are equidistant in which case round up.
Note that this is the rounding mode commonly taught at school.
In summary if you want to round a float or double to an int in java i hope this is helpful.
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.
This tutorial teaches java math class with examples.
If the argument is nan or an infinity or positive zero or negative zero.
Behaves as for roundingmode up if the discarded fraction is 0 5.
Java math class provides useful methods for performing the math s operations like exponential logarithm roots and trigonometric equations too.
Java floor method.
Another way of rounding numbers is to use math round method.
Public static double roundavoid double value int places double scale math pow 10 places.
Java int double float and mixed type arithmetic rules.
If the argument value is already equal to a mathematical integer then the result is the same as the argument.
In this case we can control n number of decimal places by multiplying and dividing by 10 n.

If the passed argument is an integer the value will not be rounded.
The floor method rounds a number downwards to the nearest integer and returns the result.
