        My little bit is a routine that calculates log to any base using
the full 15 digit internal precision.  The routine checks its arguments and
it only works when given 2 real numbers (unlike the built in log functions
which also accept complex numbers and symbolics).

To use this program enter the base into level 2 of the stack and the
number you want the log of on level 1 and run the program.

e.g. Log 3 base 2, would be calculated as:
2 ENTER 3 LOGB

[Note: Before you shout that this can be calculated by merely pressing
 3 LN 2 LN /, be aware that keyboard chain calculations like this can
 accumulate roundoff errors.  LOGB is more accurate.  See LOGB.LST for
 method and listing.  -jkh-]
