Lines Matching defs:Real
25 * \li A typedef \a Real, giving the "real part" type of \a T. If \a T is already real,
26 * then \a Real is just a typedef to \a T. If \a T is \c std::complex<U> then \a Real
45 * \li An epsilon() function which, unlike std::numeric_limits::epsilon(), returns a \a Real instead of a \a T.
