gmp_lib.mpz_sqrtrem Method

GMP Native Interface for .NET

gmp_libmpz_sqrtrem Method

Set rop1 to the truncated integer part of the square root of op, like mpz_sqrt. Set rop2 to the remainder op - rop1 * rop1, which will be zero if op is a perfect square.

Namespace: Math.Gmp.Native
Assembly: Math.Gmp.Native (in Math.Gmp.Native.dll) Version: 1.0.0.0 (1.0.0.0)

Syntax

C++

Copy

public static void mpz_sqrtrem(
	mpz_t rop1,
	mpz_t rop2,
	mpz_t op
)

Public Shared Sub mpz_sqrtrem ( 
	rop1 As mpz_t,
	rop2 As mpz_t,
	op As mpz_t
)

public:
static void mpz_sqrtrem(
	mpz_t^ rop1, 
	mpz_t^ rop2, 
	mpz_t^ op
)

static member mpz_sqrtrem : 
        rop1 : mpz_t * 
        rop2 : mpz_t * 
        op : mpz_t -> unit

Parameters

rop1: Type: Math.Gmp.Nativempz_t
The result square root integer.
rop2: Type: Math.Gmp.Nativempz_t
The result remainder integer.
op: Type: Math.Gmp.Nativempz_t
The operand integer.

Examples

C++

Copy

// Create, initialize, and set the value of op to 10000.
mpz_t op = new mpz_t();

// Create, initialize, and set the values of root and rem to 0.
mpz_t root = new mpz_t();
mpz_t rem = new mpz_t();
gmp_lib.mpz_inits(root, rem);

// Set root = trunc(sqrt(op)), and rem = op - root.

Assert.IsTrue(gmp_lib.mpz_get_si(root) == 100);
Assert.IsTrue(gmp_lib.mpz_get_si(rem) == 0);

// Release unmanaged memory allocated for root, rem, and op.
gmp_lib.mpz_clears(root, rem, op, null);
