big.Rat with sql.Scanner and driver.Valuer

I made this struct for catching decimal type BIGNUMERIC from BigQuery in Google Cloud Platform through GORM.

Types

type Rat

type Rat struct {
	*big.Rat
}

func NewFromFloat

func NewFromFloat(f float64) *Rat

func NewFromInt

func NewFromInt(i int64) *Rat

func NewFromString

func NewFromString(s string) (*Rat, error)

func NewFromUInt

func NewFromUInt(u uint64) *Rat

func (*Rat) Scan

func (r *Rat) Scan(src any) error

func (*Rat) String

func (r *Rat) String() string

func (*Rat) ToDecimal

func (r *Rat) ToDecimal(precision int32) decimal.Decimal

ToDecimal converts sqlbigrat.Rat into shopspring/decimal.Decimal, with given precision

func (*Rat) ToInt

func (r *Rat) ToInt(base, bitSize int) (int64, error)

ToInt returns integer part of sqlbigrat.Rat

func (*Rat) Value

func (r *Rat) Value() (driver.Value, error)
