Variables

var Zero = BigIntHandle{
	// contains filtered or unexported fields
}

Zero is a reference to Zero value. Zero doesn't need storage.

Types

type BigIntContainer

type BigIntContainer struct {
	// contains filtered or unexported fields
}

BigIntContainer is a structure holding the data for big.Int numbers without pointers.

func NewBigIntContainer

func NewBigIntContainer() *BigIntContainer

NewBigIntContainer constructs a new BigIntContainer.

func (*BigIntContainer) Abs

func (c *BigIntContainer) Abs(dest, x BigIntHandle) BigIntHandle

Abs sets dest to |x| (the absolute value of x).

func (*BigIntContainer) Add

func (c *BigIntContainer) Add(dest, x, y BigIntHandle) BigIntHandle

Add sets dest to the sum x+y.

func (*BigIntContainer) And

func (c *BigIntContainer) And(dest, x, y BigIntHandle) BigIntHandle

And sets dest = x & y.

func (*BigIntContainer) AndNot

func (c *BigIntContainer) AndNot(dest, x, y BigIntHandle) BigIntHandle

AndNot sets dest = x &^ y.

func (*BigIntContainer) BitLen

func (c *BigIntContainer) BitLen(x BigIntHandle) int

BitLen returns the length of the absolute value of x in bits. The bit length of 0 is 0.

func (*BigIntContainer) ByteLen

func (c *BigIntContainer) ByteLen(x BigIntHandle) int

ByteLen returns the minimum number of bytes required to represent the absolute value of x. The byte length of 0 is 0.

func (*BigIntContainer) Cmp

func (c *BigIntContainer) Cmp(x, y BigIntHandle) int

Cmp compares x and y and returns:

-1 if x <  y
 0 if x == y
+1 if x >  y

func (*BigIntContainer) CmpAbs

func (c *BigIntContainer) CmpAbs(x, y BigIntHandle) int

CmpAbs compares the absolute values of x and y and returns:

-1 if |x| <  |y|
 0 if |x| == |y|
+1 if |x| >  |y|

func (*BigIntContainer) Div

func (c *BigIntContainer) Div(dest, x, y BigIntHandle) BigIntHandle

Div sets dest to the quotient x/y for y != 0. If y == 0, a division-by-zero run-time panic occurs. Div implements Euclidean division (unlike Go); see DivMod for more details.

func (*BigIntContainer) Get

func (c *BigIntContainer) Get(handler BigIntHandle) *big.Int

Get yields a copy of a BigIntContainer number, as big.Int.

func (*BigIntContainer) GetBytes

func (c *BigIntContainer) GetBytes(x BigIntHandle) []byte

GetBytes returns the absolute value of x as a big-endian byte slice.

func (*BigIntContainer) GetUnsafe

func (c *BigIntContainer) GetUnsafe(handler BigIntHandle) *big.Int

GetUnsafe casts a BigIntContainer number to big.Int. Changing the resulting big.Int will also change the underlying data.

func (*BigIntContainer) Insert

func (c *BigIntContainer) Insert(bi *big.Int) BigIntHandle

Insert adds a copy of a big number into the BigIntContainer.

func (*BigIntContainer) InsertUint64

func (c *BigIntContainer) InsertUint64(x uint64) BigIntHandle

InsertUint64 adds a uint64 number into the BigIntContainer.

func (*BigIntContainer) IsInt64

func (c *BigIntContainer) IsInt64(x BigIntHandle) bool

IsInt64 reports whether x can be represented as an int64.

func (*BigIntContainer) Mod

func (c *BigIntContainer) Mod(dest, x, y BigIntHandle) BigIntHandle

Mod sets dest to the modulus x%y for y != 0. If y == 0, a division-by-zero run-time panic occurs. Mod implements Euclidean modulus (unlike Go); see DivMod for more details.

func (*BigIntContainer) Mul

func (c *BigIntContainer) Mul(dest, x, y BigIntHandle) BigIntHandle

Mul sets dest to the product x*y.

func (*BigIntContainer) Neg

func (c *BigIntContainer) Neg(dest, x BigIntHandle) BigIntHandle

Neg sets dest to -x.

func (*BigIntContainer) Not

func (c *BigIntContainer) Not(dest, x BigIntHandle) BigIntHandle

Not sets dest = ^x.

func (*BigIntContainer) Or

func (c *BigIntContainer) Or(dest, x, y BigIntHandle) BigIntHandle

Or sets dest = x | y.

func (*BigIntContainer) Quo

func (c *BigIntContainer) Quo(dest, x, y BigIntHandle) BigIntHandle

Quo sets dest to the quotient x/y for y != 0. If y == 0, a division-by-zero run-time panic occurs. Quo implements truncated division (like Go); see QuoRem for more details.

func (*BigIntContainer) Rem

func (c *BigIntContainer) Rem(dest, x, y BigIntHandle) BigIntHandle

Rem sets dest to the remainder x%y for y != 0. If y == 0, a division-by-zero run-time panic occurs. Rem implements truncated modulus (like Go); see QuoRem for more details.

func (*BigIntContainer) Set

func (c *BigIntContainer) Set(dest, x BigIntHandle) BigIntHandle

Set sets dest = x. It performs a copy of the data.

func (*BigIntContainer) SetBytes

func (c *BigIntContainer) SetBytes(dest BigIntHandle, buf []byte) BigIntHandle

SetBytes interprets buf as the bytes of a big-endian unsigned integer, sets dest to that value, and returns dest.

func (*BigIntContainer) SetInt64

func (c *BigIntContainer) SetInt64(dest BigIntHandle, value int64) BigIntHandle

SetInt64 sets value to dest.

func (*BigIntContainer) Sqrt

func (c *BigIntContainer) Sqrt(dest, x BigIntHandle) BigIntHandle

Sqrt sets dest to ⌊√x⌋, the largest integer such that z² ≤ x. It panics if x is negative.

func (*BigIntContainer) Sub

func (c *BigIntContainer) Sub(dest, x, y BigIntHandle) BigIntHandle

Sub sets dest to the difference x-y.

func (*BigIntContainer) ToInt64

func (c *BigIntContainer) ToInt64(x BigIntHandle) int64

ToInt64 returns the int64 representation of x. If x cannot be represented in an int64, the result is undefined.

func (*BigIntContainer) Update

func (c *BigIntContainer) Update(dest BigIntHandle, newValue *big.Int) BigIntHandle

Update replaces contents at dest with value of given argument.

func (*BigIntContainer) Xor

func (c *BigIntContainer) Xor(dest, x, y BigIntHandle) BigIntHandle

Xor sets dest = x ^ y.

type BigIntHandle

type BigIntHandle struct {
	// contains filtered or unexported fields
}

BigIntHandle acts like a pointer to a big.Int value in a BigIntContainer.
