NORMSINV function

Returns the inverse of the standard normal cumulative distribution


 * NORMSINV(probability)
 * Probability - a probability corresponding to the normal distribution.
 * If Probability is nonnumeric, NORMSINV returns the #VALUE! error value.
 * If Probability <= 0 or if Probability >= 1, NORMSINV returns the #NUM! error value.
 * Given a value for Probability, NORMSINV seeks that value z such that NORMSDIST(z) = probability.
 * NORMSINV uses an iterative search technique. If the search has not converged after 100 iterations, the function returns the #N/A error value.
