Changes

benri uses Semantic Versioning to index its versions.

v2.1.1 - Patch

  • Fixed the unit_cast not casting temperatures correctly.
  • Added unit tests to prevent this from happening in the future.

v2.1.0 - Made simple_cast and unit_cast more versatile

  • Changed simple_cast and unit_cast both from a function to a functor.
  • Both functions are now more versatile than before. The following signatures are provided:
    • simple_cast<NewQuantity>(Quantity) converts Quantity to NewQuantity.
    • simple_cast<NewQuantityPoint>(QuantityPoint) converts Quantity to NewQuantityPoint.
    • simple_cast<Unit>(Quantity) converts the unit of Quantity to Unit without changing the value_type.
    • simple_cast<Unit>(QuantityPoint) converts the unit of QuantityPoint to Unit without changing the value_type.
    • simple_cast<ValueType>(Quantity) converts the value_type of Quantity to ValueType without changing the unit.
    • simple_cast<ValueType>(QuantityPoint) converts the value_type of QuantityPoint to ValueType without changing the unit.
    • simple_cast<NewQuantity, ValueType>(Quantity) converts Quantity to unit_type of NewQuantity and a value_type of ValueType.
    • simple_cast<NewQuantityPoint, ValueType>(QuantityPoint) converts QuantityPoint to unit_type of NewQuantityPoint and a value_type of ValueType.
    • simple_cast<ValueType, NewQuantity>(Quantity) converts Quantity to unit_type of NewQuantity and a value_type of ValueType.
    • simple_cast<ValueType, NewQuantityPoint>(QuantityPoint) converts QuantityPoint to unit_type of NewQuantityPoint and a value_type of ValueType.
    • simple_cast<Unit, ValueType>(Quantity) converts the unit of Quantity to Unit and the value_type to ValueType.
    • simple_cast<Unit, ValueType>(QuantityPoint) converts the unit of QuantityPoint to Unit and the value_type to ValueType.
    • simple_cast<ValueType, Unit>(Quantity) converts the unit of Quantity to Unit and the value_type to ValueType.
    • simple_cast<ValueType, Unit>(QuantityPoint) converts the unit of QuantityPoint to Unit and the value_type to ValueType.
  • Deprecated value_type_cast because the same functionality is now provided by simple_cast.

v2.0.2 - Patch

  • Older MSVC versions had problems compiling benri due to template specialization instantiation issues. (For a proper resolution MSVC would have needed to expand certain template but did not.)
  • Fixed by adding decltype(T{}) inside the specializations.
  • Made the is_convertible_into more general. (It now removes const and volatile before type comparison.)

v2.0.1 - Second release

This is the second full release of benri. The library was improved by adding <chrono> support, fixing bugs and implementing more unit tests. Besides quality of life updates, bug fixing, and more unit tests, this seems to be the final version of benri. No further, compatibility breaking upgrades are planned for the future.

v2.0.0 - <chrono> support

  • benri now supports interaction with the <chrono> library.
  • In order to be forward-compatible with the C++20 version of <chrono>, the month and year types had to be be modified:
    • month_t is now calendar_month_t with a length of 2.592×10⁶ s.
    • year_t is now calendar_year_t with a length of 3.155 760×10⁷ s.
    • month_t maps now to the new gregorian_month_t with a length of 2.629 746×10⁶ s.
    • year_t maps now to the new gregorian_year_t with a length of 3.155 695 2×10⁷ s.
    • Because lightyear_t is a function of year_t it slightly changes as well.

v1.0.1 - Patch

  • Fixed a long existing bug in simple_cast which prevented converting quantity_point.
  • Fixed the is_quantity_point falsely taking into account cv-qualifiers.
  • Fixed non benri types not being converted into quantity when using quantity_point math.

v1.0.0 - New type conversion system

  • Replaced the is_compatible with the new convert struct.
  • The struct still provides a check if units should be implicitly convertible.
  • It now additionally handles the actual conversion.
  • This now allows us to interact with non benri types.

v0.2.0 - Improved temperatures

  • Added unit test for temperature conversion.
  • Added unit test for affine units (via temperatures).
  • Added the absolute_zero constant.

v0.1.3 - Minor patch

  • Improved cmake settings.

v0.1.2 - Minor patch

  • Fixed floating point conversion warning inside static_assert.

v0.1.1 - Minor patch

  • Some C++17 type_traits were used by mistake instead of the C++14 one.

v0.1.0 - First release

First complete user experience. Among others, the following basic functions have been implemented:

  • SI units
  • Astronomical units
  • CGS units
  • Imperial units
  • Computer Science units
  • temperatures
  • affine types
  • unit conversions
  • unit math
  • conversions between builtin types and the unit 1.
  • user defined dimensions, units and constants/symbols
  • named dimensions
  • arbitrary prefix conversions
  • unit compatibility helper
  • examples
  • unit tests
