 \description{
 The Lambert-W function is defined as the multivalued inverse of the function
 \eqn{z = f(W) = We^W}{z = f(W) = W * exp(W)}. The function has two branches. The
 principal branch is defined on the interval
-\eqn{\left[-\frac{1}{e}, \infty\right)}{[-1/e, Infinity)} and is always greater
+\eqn{\left[-\frac{1}{e}, +\infty\right)}{[-1/e, +∞)} and is always greater
 than or equal to \eqn{-1}. The second branch is defined on the interval
 \eqn{\left[-\frac{1}{e}, 0\right)}{[-1/e, 0)} and is always less than or equal
 to \eqn{-1}. The real-valued function is not defined for values less than
 \eqn{-\frac{1}{e}}{-1/e}.

 \value{
 Both functions return the appropriate values in the intervals for which they are
 defined. Outside of those intervals, they will return \code{NaN}, except that
 \code{lambertW0(Inf)} will return its limit \code{Inf} and \code{lambertWm1(0)}
 will return its limit -\code{Inf}.
