Binomial Coefficients for vli Objects

Description

binom computes binomial coefficients of vli (Very Large Integer) objects. That is, given two positive integers n and k with n >= k, the function binom(n, k) returns the number of ways to choose a subset of k elements, disregarding their order, from a set of n elements.

Usage

binom(n, k)

## Default S3 method:
binom(n, k)

## S3 method for class 'numeric'
binom(n, k)

## S3 method for class 'vli'
binom(n, k)

Arguments

n

object of class vli or 32 bits integer

k

object of class vli or 32 bits integer

Value

object of class vli
