Argument |
Description |
|---|---|
|
n |
The number for which you want the base 10 logarithm. The value of n must not be negative. |
Usage
Double.
Returns the base 10 logarithm of n. An execution error occurs if n is negative. If n is null, LogTen returns null.
Inverse of LogTen
The expression 10^n is the inverse of LogTen(n). To obtain the value of n in the equation r = LogTen(n), use n = 10^r.
Examples
This statement returns 1:
LogTen(10)
The following statements both return 0:
LogTen(1) LogTen(0)
This statement results in an execution error:
LogTen( - 2)
After the following statements execute, the value of a is 200:
double a, b = LogTen(200) a = 10^b// a = 200
