gmp_libmpq_set_num Method
Set the numerator of rational to numerator.

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 mpq_set_num(
	mpq_t rational,
	mpz_t numerator
)
Public Shared Sub mpq_set_num ( 
	rational As mpq_t,
	numerator As mpz_t
)
public:
static void mpq_set_num(
	mpq_t^ rational, 
	mpz_t^ numerator
)
static member mpq_set_num : 
        rational : mpq_t * 
        numerator : mpz_t -> unit

Parameters

rational
Type: Math.Gmp.Nativempq_t
The result rational.
numerator
Type: Math.Gmp.Nativempz_t
The operand integer.
Remarks

The function is equivalent to calling mpz_set with mpq_numref. Direct use of mpq_numref is recommended instead of this functions.

Examples
Copy
// Create, initialize, and set the value of op to -1 / 3.
mpq_t op = new mpq_t();
gmp_lib.mpq_init(op);
gmp_lib.mpq_set_si(op, -1, 3U);

// Create, initialize, and set the value of a new integer to 5.
mpz_t num = new mpz_t();
gmp_lib.mpz_init_set_ui(num, 5U);

// Set the numerator of op.
gmp_lib.mpq_set_num(op, num);

// Assert that op is 5 / 3.
Assert.IsTrue(gmp_lib.mpq_cmp_si(op, 5, 3U) == 0);

// Release unmanaged memory allocated for op and num.
gmp_lib.mpq_clear(op);
gmp_lib.mpz_clear(num);
' Create, initialize, and set the value of op to -1 / 3.
Dim op As New mpq_t()
gmp_lib.mpq_init(op)
gmp_lib.mpq_set_si(op, -1, 3UI)

' Create, initialize, and set the value of a new integer to 5.
Dim num As New mpz_t()
gmp_lib.mpz_init_set_ui(num, 5UI)

' Set the numerator of op.
gmp_lib.mpq_set_num(op, num)

' Assert that op is 5 / 3.
Assert.IsTrue(gmp_lib.mpq_cmp_si(op, 5, 3UI) = 0)

' Release unmanaged memory allocated for op and num.
gmp_lib.mpq_clear(op)
gmp_lib.mpz_clear(num)
