The list of methods to do Binomial Coefficient are organized into topic(s).

Method

longbinomialCoefficient(final int n, final int k)
Returns an exact representation of the Binomial Coefficient, " n choose k ", the number of k -element subsets that can be selected from an n -element set. 
ArithmeticUtils.checkBinomial(n, k);
if ((n == k) || (k == 0)) {
    return 1;
if ((k == 1) || (k == n - 1)) {
    return n;
if (k > n / 2) {
...
doublebinomialCoefficientDouble(final int n, final int k)
Returns a double representation of the Binomial Coefficient, " n choose k ", the number of k -element subsets that can be selected from an n -element set. 
ArithmeticUtils.checkBinomial(n, k);
if ((n == k) || (k == 0)) {
    return 1d;
if ((k == 1) || (k == n - 1)) {
    return n;
if (k > n / 2) {
...
doublebinomialCoefficientLog(final int n, final int k)
Returns the natural log of the Binomial Coefficient, " n choose k ", the number of k -element subsets that can be selected from an n -element set. 
ArithmeticUtils.checkBinomial(n, k);
if ((n == k) || (k == 0)) {
    return 0;
if ((k == 1) || (k == n - 1)) {
    return FastMath.log(n);
if (n < 67) {
...
voidcheckBinomial(final int n, final int k)
Check binomial preconditions. 
if (n < k) {
    throw new NumberIsTooLargeException(
            LocalizedFormats.BINOMIAL_INVALID_PARAMETERS_ORDER, k,
            n, true);
if (n < 0) {
    throw new NotPositiveException(
            LocalizedFormats.BINOMIAL_NEGATIVE_PARAMETER, n);
