Constructor Detail

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.
