gmp_libmpn_add_1 Method
Add {s1p, n} and s2limb, and write the n least significant limbs of the result to rp.

Namespace:  Math.Gmp.Native
Assembly:  Math.Gmp.Native (in Math.Gmp.Native.dll) Version: 1.0.0.0 (1.0.0.0)
Syntax
public static mp_limb_t mpn_add_1(
	mp_ptr rp,
	mp_ptr s1p,
	mp_size_t n,
	mp_limb_t s2limb
)

Parameters

rp
Type: Math.Gmp.Nativemp_ptr
The result integer.
s1p
Type: Math.Gmp.Nativemp_ptr
The first operand integer.
n
Type: Math.Gmp.Nativemp_size_t
The number of limbs in s1p.
s2limb
Type: Math.Gmp.Nativemp_limb_t
The second operand integer.

Return Value

Type: mp_limb_t
Return carry, either 0 or 1.
Examples
// Create multi-precision operands, and expected result.
mp_ptr s1p = new mp_ptr(new uint[] { 0xffffffff, 0xffffffff });
mp_ptr rp = new mp_ptr(new uint[2]);
mp_ptr result = new mp_ptr(new uint[] { 0x00000000, 0x00000000 });

// Set rp = s1 + 1.
mp_limb_t carry = gmp_lib.mpn_add_1(rp, s1p, s1p.Size, 1);

// Assert result of operation.
Assert.IsTrue(carry == 1);
Assert.IsTrue(rp.SequenceEqual(result));

// Release unmanaged memory.
gmp_lib.free(rp, s1p, result);
