value is any float type
A float with precision equal to value
Computes the base-ten logarithm of the float x. If the argument is less than or
equal to zero or too large, the behavior is undefined.
Note on error handling:

variable. The user can check the errno to see if an error has occurred and print
the error using the perror function.
Domain error occurs in the following cases:
