gmp_libmpf_init Method
Initialize x to 0.

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 void mpf_init(
	mpf_t x
)
Public Shared Sub mpf_init ( 
	x As mpf_t
)
public:
static void mpf_init(
	mpf_t^ x
)
static member mpf_init : 
        x : mpf_t -> unit

Parameters

x
Type: Math.Gmp.Nativempf_t
The operand float.
Remarks

Normally, a variable should be initialized once only or at least be cleared, using mpf_clear, between initializations. The precision of x is undefined unless a default precision has already been established by a call to mpf_set_default_prec.

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

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

// Assert that the value of x is 0.0.
Assert.IsTrue(gmp_lib.mpf_get_d(x) == 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 and initialize a new floating-point number x.
Dim x As New mpf_t()

gmp_lib.mpf_init(x)

' Assert that the value of x is 0.0.
Assert.IsTrue(gmp_lib.mpf_get_d(x) = 0.0)

' Release unmanaged memory allocated for x.
gmp_lib.mpf_clear(x)
