|Coefficients of an explicit Runge-Kutta method which might be used for initial-value ordinary differential equations, delay differential equations or Volterra integral equations, often require many digits for their representation. This can make manual checking of the coefficients unreliable.|
We present a dual precision package for checking the coefficients of an explicit Runge-Kutta method consisting of $k$ formulae. In some instances when a coefficient is wrong, the output from the package can be used to deduce which coefficient is likely to be wrong.
