LOG()


Syntax:     LOG(<expN>)

Purpose:    To calculate the natural logarithm of a numeric expression.

Argument:   <expN> is a number greater than zero to convert to its
            natural logarithm.

Returns:    A numeric value.

            Specifying a number less than or equal to zero returns a
            numeric overflow (a row of asterisks).

Usage:      The natural logarithm has a base of e which is 2.7183.  The
            LOG() function returns "x" in the following equation:

            e**x = y

            "y" is the specified numerical expression.  Due to
            mathematical rounding, the values returned by LOG() and
            EXP() may not agree exactly.

            LOG() is the inverse of the EXP() function.

   ? LOG(10)                     && Result: 2.30
   ? LOG(10 * 2)                 && Result: 3.00
   ? EXP(LOG(1))                 && Result: 1.00
   ? LOG(2.71)                   && Result: 1.00
