 {{mirc title|$log identifier}}'''$log''' returns the natural logarithm (base e) of a number.
-'e' is an irrational number whose digits begins with 2.718281828
-'e' is the value where graphing the curve y=e^x has slope of X at every location along the curve.
-The natural logarithm of the value N is the exponent X where e^X is the value N. $log(e) is 1, $log(1) is 0, $log of values between 0 and 1 are negative. Returns error for N=0 or N=negative.
-There may be a rounding error due to mIRC preserving fractional digits to only 6 places.
