This command returns the minimum value (positive integer) of m ( upper
bound) that satisfies the inequality formula above.

Calculation Re ult Output
x
Inv : inverse Poisson cumulative distribution
x
* Inv : recalculation value (Displayed only when there may be a possibility of
rounding error.)
• To account for possible rounding error, ClassPad additionally obtains the result
using the probability that is next lowest for the least significant digit.
For example, if the probability is 0.99999, ClassPad would recalculate using
0.99998. The recalculation result is only shown if it is different from the original
one.
