Function UpperBoundNonsortingDecimalSize

pkg/util/encoding/decimal.go:710–716

UpperBoundNonsortingDecimalSize returns the upper bound number of bytes that the decimal will need for the non-sorting encoding.

(d *apd.Decimal)

// UpperBoundNonsortingDecimalSize returns the upper bound number of bytes
// that the decimal will need for the non-sorting encoding.
func UpperBoundNonsortingDecimalSize(d *apd.Decimal) int {
	// Makeup of upper bound size:
	// - 1 byte for the prefix
	// - maxVarintSize for the exponent
	// - WordLen for the big.Int bytes
	return 1 + maxVarintSize + WordLen(d.Coeff.Bits())
}

// upperBoundNonsortingDecimalUnscaledSize is the same as
// UpperBoundNonsortingDecimalSize but for a decimal with the given unscaled
