gmp_libmpn_hamdist Method
Compute the hamming distance between {s1p, n} and {s2p, n}, which is the number of bit positions where the two operands have different bit values.

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 mp_bitcnt_t mpn_hamdist(
	mp_ptr s1p,
	mp_ptr s2p,
	mp_size_t n
)
Public Shared Function mpn_hamdist ( 
	s1p As mp_ptr,
	s2p As mp_ptr,
	n As mp_size_t
) As mp_bitcnt_t
public:
static mp_bitcnt_t mpn_hamdist(
	mp_ptr^ s1p, 
	mp_ptr^ s2p, 
	mp_size_t n
)
static member mpn_hamdist : 
        s1p : mp_ptr * 
        s2p : mp_ptr * 
        n : mp_size_t -> mp_bitcnt_t

Parameters

s1p
Type: Math.Gmp.Nativemp_ptr
The first operand integer.
s2p
Type: Math.Gmp.Nativemp_ptr
The second operand integer.
n
Type: Math.Gmp.Nativemp_size_t
The number of limbs of s1p and s2p.

Return Value

Type: mp_bitcnt_t
The hamming distance between {s1p, n} and {s2p.
Examples
Copy
// Create multi-precision operands.
mp_ptr s1p = new mp_ptr(new uint[] { 0xffffffff, 0xffffffff });
mp_ptr s2p = new mp_ptr(new uint[] { 0x00000001, 0xffffffff });

// Assert hamming distance.
Assert.IsTrue(gmp_lib.mpn_hamdist(s1p, s2p, s1p.Size) == 31);

// Release unmanaged memory.
gmp_lib.free(s1p, s2p);
' Create multi-precision operands.
Dim s1p As New mp_ptr(New UInteger() { &HffffffffUI, &HffffffffUI})
Dim s2p As New mp_ptr(New UInteger() { &H1, &HffffffffUI})

' Assert hamming distance.
Assert.IsTrue(gmp_lib.mpn_hamdist(s1p, s2p, s1p.Size) = 31)

' Release unmanaged memory.
gmp_lib.free(s1p, s2p)
