# Binomial Coefficient (G Dataflow)

Calculates the binomial coefficient for two nonnegative integer values.  ## n

A nonnegative integer. ## k

A nonnegative integer. ## error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error  If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.

Default: No error ## binomial coefficient

Result of the calculation of the binomial coefficient for the given values of n and k. ## error out

Error information.

The node produces this output according to standard error behavior.

## Algorithm for Calculating the Binomial Coefficient

The following equation defines the binomial coefficient.

$\left(\begin{array}{c}n\\ k\end{array}\right)=\frac{n!}{k!\left(n-k\right)!}$
