Syntax
LOGARITHM_N(Argument)
Description
The LOGARITHM_N SQL scalar function returns the natural logarithm (e) of a number. The LOGARITHM_N and EXPONENTIAL functions are inverse operations.
The argument must be a number.
The data type of the result is double-precision floating point.
If the argument can be null, the result can be null; if the argument is null, the result is the null value.
Example
Assume the column NATLOG is a decimal (4,2) column with a value of 31.62.
LOGARITHM_N(NATLOG)
Returns the approximate value 3.45.
