Ln Returns Natural Logarithm of x
Ln(X : Real) : Real;
Ln(X : Integer) : Real;
Returns the natural logarithm of X--i.e., the log (base e) of X.
X An integer or real value (constant, variable, function
call, or expression).
Limits: if X <= 0, runtime error 4 ($4) occurs.
Notes: The value e is approximately 2.71828182846 and has
special significance in mathematics. Note that
Exp(Ln(X)) = X.
-------------------------------- Example ---------------------------------
X := Ln(42); { X = 3.7376696183 }
