This section describes literal suffixes for constructing complex number literals
.The suffixes
i,
il, and
if create complex numbers of
the types
complex<double>,
complex<long double>, and
complex<float> respectively, with their imaginary part denoted by the
given literal number and the real part being zero
.constexpr complex<long double> operator""il(long double d);
constexpr complex<long double> operator""il(unsigned long long d);
Returns:
complex<long double>{0.0L, static_cast<long double>(d)}. constexpr complex<double> operator""i(long double d);
constexpr complex<double> operator""i(unsigned long long d);
Returns:
complex<double>{0.0, static_cast<double>(d)}. constexpr complex<float> operator""if(long double d);
constexpr complex<float> operator""if(unsigned long long d);
Returns:
complex<float>{0.0f, static_cast<float>(d)}.
