gmp_libmpz_fdiv_r_2exp Method
Set the remainder r to n - q * 2^b where q = floor(n / 2^b).

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_fdiv_r_2exp(
	mpz_t r,
	mpz_t n,
	mp_bitcnt_t b
)

Parameters

r
Type: Math.Gmp.Nativempz_t
The result remainder integer.
n
Type: Math.Gmp.Nativempz_t
The numerator integer.
b
Type: Math.Gmp.Nativemp_bitcnt_t
The exponent of the power of two denominator.
Examples
// Create, initialize, and set the value of n to 10001.
mpz_t n = new mpz_t();
gmp_lib.mpz_init_set_si(n, 10001);

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

// Set r = n - 2^2 * floor(n / 2^2)
gmp_lib.mpz_fdiv_r_2exp(r, n, 2U);

// Assert that r is 1.
Assert.IsTrue(gmp_lib.mpz_get_si(r) == 1);

// Release unmanaged memory allocated for n and r.
gmp_lib.mpz_clears(n, r, null);
