.. function:: log(x[, base])
Return the logarithm of *x* to the given *base*. If the *base* is not specified,
return the natural logarithm of *x* (that is, the logarithm to base *e*).
With one argument, return the natural logarithm of *x* (to base *e*).
With two arguments, return the logarithm of *x* to the given *base*,
calculated as ``log(x)/log(base)``.
