Types

type Num

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

func FromBigInt

func FromBigInt(v *big.Int) (n Num)

func FromDecimal128

func FromDecimal128(n decimal128.Num) Num

func FromFloat32

func FromFloat32(v float32, prec, scale int32) (Num, error)

func FromFloat64

func FromFloat64(v float64, prec, scale int32) (Num, error)

func FromI64

func FromI64(v int64) Num

func FromString

func FromString(v string, prec, scale int32) (n Num, err error)

func FromU64

func FromU64(v uint64) Num

func GetHalfScaleMultiplier

func GetHalfScaleMultiplier(pow int) Num

func GetMaxValue

func GetMaxValue(prec int32) Num

func GetScaleMultiplier

func GetScaleMultiplier(pow int) Num

func Max

func Max(first Num, rest ...Num) Num

Max returns the largest Decimal256 that was passed in the arguments

func Min

func Min(first Num, rest ...Num) Num

Min returns the smallest Decimal256 that was passed in the arguments

func New

func New(x1, x2, x3, x4 uint64) Num

New returns a new signed 256-bit integer value where x1 contains the highest bits with the rest of the values in order down to the lowest bits

ie: New(1, 2, 3, 4) returns with the elements in little-endian order
    {4, 3, 2, 1} but each value is still represented as the native endianness

func (Num) Abs

func (Num) Add

func (n Num) Add(rhs Num) Num

func (Num) Array

func (n Num) Array() [4]uint64

func (Num) BigInt

func (n Num) BigInt() *big.Int

func (Num) Cmp

func (n Num) Cmp(other Num) int

Cmp compares the numbers represented by n and other and returns:

+1 if n > other
 0 if n == other
-1 if n < other
