Function encodeNonsortingDecimalValue

postgres/parser/encoding/decimal.go:615–621

encodeNonsortingDecimalValue encodes the absolute value of a decimal's exponent and slice of digit bytes into buf, returning the populated buffer after encoding. The function first encodes the absolute value of a decimal's exponent as an unsigned varint. Following this, it copies the decimal's big-e

(exp uint64, digits []big.Word, buf []byte)

// decimal's exponent as an unsigned varint. Following this, it copies the
// decimal's big-endian digits themselves into the buffer.
func encodeNonsortingDecimalValue(exp uint64, digits []big.Word, buf []byte) []byte {
	// Encode the exponent using a Uvarint.
	buf = EncodeUvarintAscending(buf, exp)

	// Encode the digits into the end of the byte slice.
	return copyWords(buf, digits)
}

func encodeNonsortingDecimalValueWithoutExp(digits []big.Word, buf []byte) []byte {
	// Encode the digits into the end of the byte slice.
