Function Documentation

operator!=()

const Einteger computefhe::operator!=	(	double	a,
		const Efixedpoint &	b
	)

Parameters

a	The plaintext double value.
b	The encrypted fixed-point value.

Returns

An Einteger representing the encrypted boolean result (1 if not equal).

operator*()

		const Efixedpoint &	b
	)

Parameters

a	The plaintext double value.
b	The encrypted fixed-point value.

Returns

A new Efixedpoint representing the encrypted product (a * b).

operator+()

const Efixedpoint computefhe::operator+	(	double	a,
		const Efixedpoint &	b
	)

Parameters

a	The plaintext double value.
b	The encrypted fixed-point value.

Returns

A new Efixedpoint representing the encrypted sum (a + b).

operator-()

		const Efixedpoint &	b
	)

Parameters

a	The plaintext double value.
b	The encrypted fixed-point value.
