gmp_libmpz_mul_2exp Method
Set rop to op1 * 2^op2.

Namespace:  Math.Gmp.Native
Assembly:  Math.Gmp.Native (in Math.Gmp.Native.dll) Version: 1.0.0.0 (1.0.0.0)
Syntax
public static void mpz_mul_2exp(
	mpz_t rop,
	mpz_t op1,
	mp_bitcnt_t op2
)

Parameters

rop
Type: Math.Gmp.Nativempz_t
The result integer.
op1
Type: Math.Gmp.Nativempz_t
The first operand integer.
op2
Type: Math.Gmp.Nativemp_bitcnt_t
The second operand integer.
Remarks

This operation can also be defined as a left shift by op2 bits.

Examples
// Create, initialize, and set the value of x to -10000.
mpz_t x = new mpz_t();
gmp_lib.mpz_init_set_si(x, -10000);

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

// Set z = -10000 * 2^2.
gmp_lib.mpz_mul_2exp(z, x, 2U);

// Assert that z is -40000.
Assert.IsTrue(gmp_lib.mpz_get_si(z) == -10000 * 4);

// Release unmanaged memory allocated for x and z.
gmp_lib.mpz_clears(x, z, null);
