Syntax
Copy
public static int mpf_get_si(
	mpf_t op
)
Public Shared Function mpf_get_si ( 
	op As mpf_t
) As Integer
public:
static int mpf_get_si(
	mpf_t^ op
)
static member mpf_get_si : 
        op : mpf_t -> int

Parameters

op
Type: Math.Gmp.Nativempf_t
The operand float.

Return Value

Type: Int32
The converted integer.
Remarks

If op is too big for the return type, the result is undefined.

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

// Create, initialize, and set a new floating-point number to -8.0
mpf_t x = new mpf_t();
gmp_lib.mpf_init_set_d(x, -8.0);

// Assert that the value of x is -8.
Assert.IsTrue(gmp_lib.mpf_get_si(x) == -8);

// 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 to -8.0
Dim x As New mpf_t()
gmp_lib.mpf_init_set_d(x, -8.0)

' Assert that the value of x is -8.
Assert.IsTrue(gmp_lib.mpf_get_si(x) = -8)

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