Syntax
public static void mpf_sub(
	mpf_t rop,
	mpf_t op1,
	mpf_t op2
)

Parameters

rop
Type: Math.Gmp.Nativempf_t

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 10.
mpf_t x = new mpf_t();
gmp_lib.mpf_init_set_si(x, 10);

// Create, initialize, and set a new floating-point number y to -210.
mpf_t y = new mpf_t();
gmp_lib.mpf_init_set_si(y, -210);

// Create and initialize a new floating-point number z.
mpf_t z = new mpf_t();
gmp_lib.mpf_init(z);

// Set z = x - y.
gmp_lib.mpf_sub(z, x, y);

// Assert that the value of z is 220.
Assert.IsTrue(gmp_lib.mpf_get_d(z) == 220.0);

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