The calculation results of invGeoCDf are integers. Accuracy may be reduced when the
first argument has 10 or more digits. Note that even a slight difference in calculation
accuracy affects calculation results. If a warning message appears, check the displayed
values.

Important!
When executing the invHypergeoCDf function the calculator uses the specified
value and the value that is one less the
