Binomial

Binomial
gives the binomial coefficient .
  • Integer mathematical function, suitable for both symbolic and numerical manipulation.
  • In general, is defined by or suitable limits of this.
  • For integers and certain other special arguments, Binomial automatically evaluates to exact values.
  • Binomial is automatically evaluated symbolically for simple cases; FunctionExpand gives results for other cases.
  • Binomial can be evaluated to arbitrary numerical precision.
  • Binomial automatically threads over lists.
