Namespace:  Math.Gmp.Native
Assembly:  Math.Gmp.Native (in Math.Gmp.Native.dll) Version: 1.0.0.0 (1.0.0.0)
Syntax
Copy
public static int mpf_cmp_d(
	mpf_t op1,
	double op2
)
Public Shared Function mpf_cmp_d ( 
	op1 As mpf_t,
	op2 As Double
) As Integer
public:
static int mpf_cmp_d(
	mpf_t^ op1, 
	double op2
)
static member mpf_cmp_d : 
        op1 : mpf_t * 
        op2 : float -> int

Parameters

op1
Type: Math.Gmp.Nativempf_t
The first operand float.
op2
Type: SystemDouble
The second operand float.

Return Value

Type: Int32
Return a positive value if op1 > op2, zero if op1 = op2, and a negative value if op1 < op2.
Remarks

mpf_cmp_d can be called with an infinity, but results are undefined for a NaN.

Examples
Copy
// 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.
gmp_lib.mpf_clear(x);
' Set default precision to 64 bits.
gmp_lib.mpf_set_default_prec(64UI)

' Create, initialize, and set a new floating-point number x to 512.
Dim x As 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.
gmp_lib.mpf_clear(x)
