It is "n choose k", the number of k-element subsets that
can be selected from an n-element set.| Modifier and Type | Method and Description |

Computes the binomial coefficient.

public static double value(int n, int k)
The largest value of n for which all coefficients can
fit into a double is 1029. Larger n may result in
infinity depending on the value of k.
Any min(k, n - k) >= 515 cannot fit into a double
and will result in infinity.
n - Size of the set.k - Size of the subsets to be counted.n choose k.IllegalArgumentException - if n < 0, k < 0 or k > n.Copyright © 2017–2022 The Apache Software Foundation. All rights reserved.
