Determines the base 10 logarithm of a number.
LogTen ( n )
Argument |
Description |
---|---|
n |
The number for which you want the base 10 logarithm. The value of n must not be negative. |
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
.
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
