For given
A and
X is
LOGA(X)=LN(X)/LN(A) where the
LN function is
natural logarithm. The most useful numbers for us in this connection are
LN(2) and
LN(10). There are two simple function returning first
200 decimal digits of these constants. For their computation I used an algorithm from
Natural logarithm, see the
LN2P function. And the program for automatic creating a function from value of constant, see
Technique: Beforehand computed constants.
