      • SqrtRatio

        protected SqrtRatio​(boolean isQR,
                    java.math.BigInteger ratio)
        Constructs an instance of SqrtRatio representing the result of a square root ratio computation.
        Parameters:
        isQR - A boolean flag indicating whether the computed value is a quadratic residue (QR) modulo a specific field. This helps determine if the ratio under consideration has a valid square root.
        ratio - The ratio value resulting from the square root ratio computation.

    • Method Detail

      • isQR

        public boolean isQR()
        Checks whether the computed value is a quadratic residue (QR) modulo a specific field.
        Returns:
        true if the computed value is a quadratic residue (QR); false otherwise.

      • getRatio

        public java.math.BigInteger getRatio()
        Retrieves the ratio value resulting from the square root ratio computation.
        Returns:
        the ratio value as a BigInteger.
