Functions

func FromBytes

func FromBytes(data []byte) *big.Int

FromBytes converts data in little-endian format to an integer.

func FromBytesUnsigned

func FromBytesUnsigned(data []byte) *big.Int

FromBytesUnsigned converts data in little-endian format to an unsigned integer.

func ToBytes

func ToBytes(n *big.Int) []byte

ToBytes converts integer to a slice in little-endian format. Note: NEO3 serialization differs from default C# BigInteger.ToByteArray()

when n == 0. For zero is equal to empty slice in NEO3.

func ToPreallocatedBytes

func ToPreallocatedBytes(n *big.Int, data []byte) []byte

ToPreallocatedBytes converts integer to a slice in little-endian format using given byte array for conversion result.
