Warning: The parameter to the function was not a positive numeric value
Description
The Log and Ln mathematical functions both act on a value that must be positive. If they are given a negative value, or zero, the result is undefined.
When used in a procedure, if the expression used in the Log or Ln function is zero or negative, this warning will be generated and the function will return #N/A.
