+\description{
+ Inverse of the arithmetic power function \code{\link{powfunc}} used for
+ modelling univariate nonlinear calibration data. }

+\value{
+ The result of evaluating the function
+ \deqn{f(x) = \frac{y}{a}^\frac{1}{b}}{f(x) = y/a^1/b}
+ which is the inverse of the function defined by \code{\link{powfunc}}
