---------------------------------------------------------------
The log function is undefined for all x < 0.
The log is an exponent of a base used to express positive numbers.
Powers of a positive base connot express negative numbers,
so logs are not defined for negative numbers.
The exponent (log) can be negative but the antilog cannot be negative.
