real_t

template<typename Scalar >

using molpro::linalg::itsolv::log::real_t = typedef decltype(std::abs(std::declval<Scalar>()))

The real type associated with a (possibly complex) scalar type, e.g. the type of norms and errors

Function Documentation

compose()

std::string molpro::linalg::itsolv::log::compose ( std::string_view  message, std::string_view  suffix  )

inline

Returns

message with the given suffix appended. A separator is inserted if the message doesn't end in a blank.

stringify()

template<typename T >
requires stringifiable<T>

std::string molpro::linalg::itsolv::log::stringify	(	const T &	t,
		std::size_t	precision = default_precision
	)

Converts the given object into a string.

Ranges are printed as [a, b, ...], pair-like objects as { first: second }. Anything else is formatted via std::format or, failing that, operator<<.

Parameters

precision

Number of significant digits for floating-point values (and complex numbers of them). Types whose std::formatter understands a ".N" precision specification (e.g. subspace::Matrix) receive it as well.

Variable Documentation

default_precision

constexpr const std::size_t molpro::linalg::itsolv::log::default_precision = std::numeric_limits<std::size_t>::max()

constexpr

Constant indicating that formatting should be done with default precision
