CHIINV function

Returns the inverse of the right-tailed probability of the chi-squared distribution.


 * If probability < 0, the CHIINV function will return the #NUM! error.
 * If probability > 1, the CHIINV function will return the #NUM! error.
 * If probability is not numeric, the CHIINV function will return the #VALUE! error.
 * If degrees < 1, the CHIINV function will return the #NUM! error.
 * If degrees > 1010, the CHIINV function will return the #NUM! error.
 * If degrees is not numeric, the CHIINV function will return the #VALUE! error.
