底数)LN（真数）以e为底的对数。对数LOG(number,base)Number 为用于计算对数的正实数。Base 为对数的底数。如果省略底数，假定其值为 10。***********=EXP(1) e 的近似值 (2.718282)=EXP(2) 自然对数的底数 e 的 2 次幂 (7.389056 )
The number and base arguments in theLOGfunction must be greater than zero.If a negative or zero value is used for any argument, theLOGfunction returns a#NUM!error. Non-Numeric Arguments Cause #VALUE! Error The arguments of theLOGfunction can’t be text values, either. If a text value is...
Function notes Number, the only argument in the LOG10 function, should be supplied as a numeric value. LOG10 function will return the #VALUE! error if number is non-numeric. LOG function will return the #NUM! error if number ≤ 0. In LOG function, when the base argument is omitted, ...
【参数】Number 是计算对数的任意实数,Base 是对数的底数。如果省略底数,则默认它的值为 10。 【实例】如果 A1=8,则公式“=LOG(A1,2)”返回 3;=LOG(100,10)返回 2。 25、Excel数学与三角函数:LOG10 【用途】返回以 10 为底的对数。 【语法】LOG10(number) 【参数】Number 是待计算常用对数的一个正实...
语法: LOG(number,base) 参数: Number是计算对数的任意实数,Base是对数的底数。如果省略底数,则默认它的值为10。 实例: 如果A1=8,则公式“=LOG(A1,2)”返回3;=LOG(100,10)返回2。 25.LOG10 用途: 返回以10为底的对数。 语法: LOG10(number) 参数: Number是待计算常用对数的一个正实数。
i.e. If ax= b Then Loga(b) = x. LOG Formula in Excel Below is the LOG Formula in Excel : or Explanation of LOG Function in Excel LOG formula in Excel consists of two things Number & Base. Number= It is a positive real number that you want to calculate the logarithm in Excel. ...
Method 1 – Use Excel LOG Function The LOG function computes the logarithm of a number to a particular base. In order to use the LOG function, select a cell and enter the function as shown below. Steps: To find log base 2, select an output cell (In this example, D5). Enter the ...
