If the passed argument is an integer the value will not be rounded. Math ceil 1000000000000000000l 1 2 0. Java math class provides useful methods for performing the math s operations like exponential logarithm roots and trigonometric equations too. Java ceil method the method ceil gives the smallest integer that is greater than or equal to the argument.

More precisely for a number x floor x is the largest integer less than or equal to x and ceiling x is the smallest integer. If the argument is integer then the result is integer. The floor and ceil map the given number to the largest previous or the smallest following integer respectively.

Given a sorted array of integers find floor and ceil of a given number in it. 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.
