Examples
// Set default precision to 64 bits.
gmp_lib.mpf_set_default_prec(64U);

// Create, initialize, and set a new floating-point number x to 512.
mpf_t x = new mpf_t();
gmp_lib.mpf_init_set_si(x, 512);

// Assert that x > 128.0.
Assert.IsTrue(gmp_lib.mpf_cmp_d(x, 128.0) > 0);

// Release unmanaged memory allocated for x.
