Syntax: factorial(n::Integer)

Parameters:

• n: Specified number

Returns: It returns the factorial of the specified number n.

Example 1:

# Julia program to illustrate
# the use of factorial() method

# Getting the factorial of
# the specified number
println(factorial(0))
println(factorial(1))
println(factorial(2))

Output:

1
1
2

Example 2:

# Julia program to illustrate
# the use of factorial() method

# Getting the factorial of
# the specified number
println(factorial(5))
println(factorial(7))
println(factorial(big(20)))
println(factorial(big(15)))

Output:

120
