The change to the value of a variable as a result of cascading is only printed
if the change is deemed significant. The change is tested against: absolute and relative
convergence tolerance and absolute and relative cascading print tolerance. The change is
printed only if all tests fail. The relative cascading print criterion measures the
change in value of a variable (
X) relative to the value of the
variable (
X), against the relative cascading print tolerance. If
X < X * XSLP_CASCADETOL_PR
then the change is within the relative cascading print tolerance and will not be printed.
