Functions ¶

func Append ¶

func Append(p []byte, x *big.Int) []byte

func BigIntToByte ¶

func BigIntToByte(x *big.Int, precision, scale uint32) (p [16]byte)

BigIntToByte returns the 16-byte array representation of x.

If x value does not fit in 16 bytes with given precision, it returns 16-byte representation of infinity or negative infinity value accordingly to x's sign.

func Err ¶

func Err() *big.Int

Err returns "error" value.

func Format ¶

func Format(x *big.Int, precision, scale uint32) string

Format returns the string representation of x with the given precision and scale.

func FromBytes ¶

func FromBytes(bts []byte, precision, scale uint32) *big.Int

FromBytes converts bytes representation of decimal to big integer. Most callers should use FromInt128().

If given bytes contains value that is greater than given precision it returns infinity or negative infinity value accordingly the bytes sign.

func FromInt128 ¶

func FromInt128(p [16]byte, precision, scale uint32) *big.Int

FromInt128 returns big integer from given array. That is, it interprets 16-byte array as 128-bit integer.

func Inf ¶

func Inf() *big.Int

Inf returns infinity value.

func IsErr ¶

func IsErr(x *big.Int) bool

IsErr reports whether x is an "error" value.

func IsInf ¶

func IsInf(x *big.Int) bool

IsInf reports whether x is an infinity.

func IsNaN ¶

func IsNaN(x *big.Int) bool

IsNaN reports whether x is a "not-a-number" value.

func NaN ¶

func NaN() *big.Int

NaN returns "not-a-number" value.

func Parse ¶

func Parse(s string, precision, scale uint32) (*big.Int, error)

Parse interprets a string s with the given precision and scale and returns the corresponding big integer.

Types ¶

type ParseError ¶

type ParseError struct {
	Err   error
	Input string
}

func (*ParseError) Error ¶

func (p *ParseError) Error() string

func (*ParseError) Unwrap ¶

func (p *ParseError) Unwrap() error
