Getting binomial coefficient of a number in Julia – binomial() Method
The
binomial()
is an inbuilt function in
julia which is used to return the binomial coefficient
which is the coefficient of the kth term in the polynomial expansion of
.
Its formula is –
, where
is the factorial of
n.
If n is negative, then it is defined in terms of the identity
.
Syntax: binomial(n::Integer, k::Integer)
Parameters:
- n: Specified number
- k: Specified number
Returns: It returns the binomial coefficient .
Example 1:
println(binomial( 6 , 4 ))
println(factorial( 6 ) ÷ (factorial( 6 - 4 ) * factorial( 4 )))
|
Output:
15
15
Example 2:
println(binomial( 6 , 3 ))
println(binomial( - 6 , 3 ))
println(binomial( - 6 , - 2 ))
println(binomial( 5 , 2 ))
|
Output:
