Types

type Number

type Number struct {
	RawValue *big.Int `json:"raw"`
	Decimals int      `json:"decimals"`
}

Number the fixed number present object

func New

func New(decimals int, source Source) (*Number, error)

New create fixed number object

func (*Number) Add

func (number *Number) Add(other *Number) *Number

Add x add y and return new fixed number object

func (*Number) Cmp
