Excel必会函数:Round/ABS/INT/MOD函数
在Excel中，如果说哪一类函数使用频率相对来说较高的话，数学类的函数应该会是其中之一，理由很简单：Excel中大部分的数据都是数字。
在今天，我们继续讨论接下来的函数：数学函数，包括Round及相关函数、Abs函数、SQRT函数、Power函数、INT函数、MOD函数、Product函数，虽说看起来很多，但相对来说，这些函数的使用都比较简单。
一、Round及相关函数--四舍五入函数。
Round函数：
中文定义：四舍五入
函数定义：=ROUND（数值，保留几位小数）
参数说明：
①：数值：想要四舍五入的具体数值
②：保留几位小数：根据需要保留小数点
从函数的定义来看，这个函数还是比较简单的，接下来，通过案例来加深印象：
将0.56这个数值四舍五入：
2、Roundup函数：向上四舍五入函数。
通常情况下，Round函数就是向上四舍五入的函数，而这个Roundup函数则与Round函数有些无区别。
功能定义：向上四舍五入函数
函数定义：=ROUNDUP（数字，保留位数）
参数说明：
①：数字：要向上舍入的数字
②：保留位数：要保留的小数位数，其中，保留的小数位数为正数的话，则向小数点右侧数，若保留的小数位数为负数，则向小数点左侧数。
接下来，便是看下相关案例：
1、常规用法-这种用法与Round相似。
2、专属于Roundup函数的用法:
感兴趣的小伙伴可以思考一下，为什么会是这个答案哦。
同理，有roundup函数，自然也有对应的rounddown函数，用法几乎一致，这里就不做过多的说明了。
二、ABS函数。
这个函数相信小伙伴都认识：绝对值函数。在初中数学中应该也学过相关的用法，简单来说，就是求绝对值。
功能定义：求取绝对值
函数定义：=ABS（数值）
举例：求绝对值
三、SQRT函数。
功能定义：求取指定数值的平方根
函数定义：=SQRT（数值）
举例：求平方根
四、Power函数
功能定义：求出指定数值的幂运算的值
函数定义：=power（数值，幂）
参数说明：
①：数值：想要实现幂运算的值
②：幂：幂的具体数值
举例：
五、INT函数。
功能定义：将小数变为整数（将数字向下取整，把小数部分直接去掉，不考虑四舍五入）
函数定义：=INT（数字）
举例：
六、MOD函数。
功能定义：计算两数相除的余数
函数定义：=MOD（被除数，除数）
参数说明：
①：被除数：可以是直接输入的数字、单元格引用或数组
②：除数：可以是直接输入的数字、单元格引用或数组
注意点：
①：被除数不能是0
②：如果被除数和除数同为正数或负数，Mod返回余数
举例：
七：Product函数
功能定义：计算数字的乘积
函数定义：=product（数字1，数字2）
举例：
好了，以上便是今天关于Excel函数的相关内容啦，虽说函数比较多，但相关的函数都比较简单，希望能帮到你，下次见~~
