BINOMIALCOEF Function

Evaluates the binomial coefficient.

Usage

result = BINOMIALCOEF(n, m)

Input Parameters

n—First parameter of the binomial coefficient. Parameter n must be nonnegative.

m—Second parameter of the binomial coefficient. Parameter m must be nonnegative.

Returned Value

result—The binomial coefficient:

 

is returned.

Input Keywords

Double—If present and nonzero, double precision is used.

Discussion

The binomial function is defined to be:

 

with n ³ m ³ 0. Also, n must not be so large that the function overflows.

Example

In this example:

 

is computed and printed.

n  =  9

m  =  5

ans  =  BINOMIALCOEF(n, m)

PRINT,  'binomial coefficient =', ans

; PV-WAVE prints: binomial coefficient =      126.000
