geomv

double geomv(double pp, double p, int *x0, int *x1);

Returns two critical points of the Geometric random variable distribution function with probability of success p such that P(X ≤ x0) ≤ pp ≤ P(X ≤ x1).

Parameters:
ppCummulative probability.
pProbability of success.
x0Lower bound critical point.
x1Upper bound critical point.

Returns:
On exit, x0 and x1 are set such thate P(X ≤ x0 | p) ≤ pp ≤ P(X ≤ x1 | p)

Errors:
NUM_ERRROR is raise if p ≤ 0, p ≥ 1, pp ≤ 0, or pp ≥ 1

Usage:
int x0, x1;
geomv(0.5, 0.75, &x0, &x1)
