Certainly Kurt's reply to look at the documentation is a good one. Putting in known constants that give known results is an alternative way or at least a way that might help you remember in the future. log(e) = 1, e ** 1 = e, etc.
data; x = log(constant('e')); put x; x = log10(10); put x; x = exp(log(constant('e'))); put x; run;
