Mathf.Round 四舍五入

static function Round (f : float) : float

Description描述

Returns f rounded to the nearest integer.

返回浮点数 f 进行四舍五入最接近的整数。

If the number ends in .5 so it is halfway between two integers, one of which is even and the other odd, the even number is returned.

如果数字末尾是.5,因此它是在两个整数中间,不管是偶数或是奇数,将返回偶数。
