LOG()

    LOG() returns the natural logarithm of a specified number.

Syntax

    LOG(<exp N>)

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 (2.7183).  LOG() returns the
    exponent in the following equation:

    e to the xth power = y

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