Syntax
Copy
public static void mpz_2fac_ui(
	mpz_t rop,
	uint n
)
Public Shared Sub mpz_2fac_ui ( 
	rop As mpz_t,
	n As UInteger
)
public:
static void mpz_2fac_ui(
	mpz_t^ rop, 
	unsigned int n
)
static member mpz_2fac_ui : 
        rop : mpz_t * 
        n : uint32 -> unit

Examples
Copy
// Create, initialize, and set the value of rop to 0.
mpz_t rop = new mpz_t();
gmp_lib.mpz_init(rop);

// Set rop = 9!!.
gmp_lib.mpz_2fac_ui(rop, 9U);

// Assert that rop is 945.
Assert.IsTrue(gmp_lib.mpz_get_si(rop) == 945);

// Release unmanaged memory allocated for rop.
gmp_lib.mpz_clear(rop);
' Create, initialize, and set the value of rop to 0.
Dim rop As New mpz_t()
gmp_lib.mpz_init(rop)

' Set rop = 9!!.
gmp_lib.mpz_2fac_ui(rop, 9UI)

' Assert that rop is 945.
Assert.IsTrue(gmp_lib.mpz_get_si(rop) = 945)

' Release unmanaged memory allocated for rop.
gmp_lib.mpz_clear(rop)
