◆ abs()

template<typename _Rep , typename _Period >

constexpr enable_if_t< numeric_limits< _Rep >::is_signed, duration< _Rep, _Period > > std::chrono::abs ( duration< _Rep, _Period > __d )

constexpr

The absolute (non-negative) value of a duration.

Parameters

__d	A duration with a signed `rep` type.

Returns: A duration of the same type as the argument, with value |d|.

Since: C++17

Definition at line 435 of file chrono.h.

References std::abs().

◆ ceil() [1/2]

template<typename _ToDur , typename _Rep , typename _Period >

constexpr __enable_if_is_duration< _ToDur > std::chrono::ceil ( const duration< _Rep, _Period > & __d )

constexpr

Convert a duration to type ToDur and round up.

If the duration cannot be represented exactly in the result type, returns the closest value that is greater than the argument.

Template Parameters

_ToDur The result type must be a duration.

Parameters

__d	A duration.

Returns: The value of __d converted to type _ToDur.

Since: C++17

Definition at line 384 of file chrono.h.

constexpr enable_if_t< __is_duration< _ToDur >::value, time_point< _Clock, _ToDur > > std::chrono::ceil ( const time_point< _Clock, _Dur > & __tp )

constexpr

Convert a time_point to type ToDur and round up.

The result is the same time point as measured by the same clock, but using the specified duration to represent the time. If the time point cannot be represented exactly in the result type, returns the closest value that is greater than the argument.

Template Parameters

_ToDur The duration type to use for the result.

Parameters

__t	A time point.

Returns: The value of __d converted to type _ToDur.

Since: C++17

Definition at line 1053 of file chrono.h.

◆ duration_cast()

template<typename _ToDur , typename _Rep , typename _Period >

constexpr __enable_if_is_duration< _ToDur > std::chrono::duration_cast ( const duration< _Rep, _Period > & __d )

constexpr

Convert a duration to type ToDur.

If the duration cannot be represented accurately in the result type, returns the result of integer truncation (i.e., rounded towards zero).

Template Parameters

_ToDur The result type must be a duration.

Parameters

__d	A duration.

Returns: The value of __d converted to type _ToDur.

Since: C++11

Definition at line 262 of file chrono.h.

◆ floor() [1/2]

template<typename _ToDur , typename _Rep , typename _Period >

constexpr __enable_if_is_duration< _ToDur > std::chrono::floor ( const duration< _Rep, _Period > & __d )

constexpr

Convert a duration to type ToDur and round down.

If the duration cannot be represented exactly in the result type, returns the closest value that is less than the argument.

Template Parameters

_ToDur The result type must be a duration.

Parameters

__d	A duration.

Returns: The value of __d converted to type _ToDur.

Since: C++17

Definition at line 364 of file chrono.h.

◆ floor() [2/2]

template<typename _ToDur , typename _Clock , typename _Dur >

constexpr

Convert a time_point to type ToDur and round down.

The result is the same time point as measured by the same clock, but using the specified duration to represent the time. If the time point cannot be represented exactly in the result type, returns the closest value that is less than the argument.

Template Parameters

_ToDur The duration type to use for the result.

Parameters

__t	A time point.

Returns: The value of __d converted to type _ToDur.

constexpr

Convert a duration to type ToDur and round to the closest value.

If the duration cannot be represented exactly in the result type, returns the closest value, rounding ties to even.

Template Parameters

_ToDur The result type must be a duration with a non-floating-point rep type.

Parameters

__d	A duration.

Returns: The value of __d converted to type _ToDur.

Since: C++17

Definition at line 409 of file chrono.h.

◆ round() [2/2]

constexpr

Convert a time_point to type ToDur and round to the closest value.

The result is the same time point as measured by the same clock, but using the specified duration to represent the time. If the time point cannot be represented exactly in the result type, returns the closest value, rounding ties to even.

Template Parameters

_ToDur The duration type to use for the result, which must have a non-floating-point rep type.

Parameters

__t	A time point.

Returns: The value of __d converted to type _ToDur.

Since: C++17

constexpr __enable_if_t< __is_duration< _ToDur >::value, time_point< _Clock, _ToDur > > std::chrono::time_point_cast ( const time_point< _Clock, _Dur > & __t )

constexpr

Convert a time_point to use duration type ToDur.

The result is the same time point as measured by the same clock, but using the specified duration to represent the time. If the time point cannot be represented accurately in the result type, returns the result of integer truncation (i.e., rounded towards zero).

Template Parameters

_ToDur The duration type to use for the result.

Parameters

__t	A time point.

Returns: The value of __t converted to use type _ToDur.
