* Augment NumTraits with min/max_exponent() again.Gravatar Antonio Sanchez2021-03-16
| | | | | | | | | | | | Replace usage of `std::numeric_limits<...>::min/max_exponent` in codebase where possible. Also replaced some other `numeric_limits` usages in affected tests with the `NumTraits` equivalent. The previous MR !443 failed for c++03 due to lack of `constexpr`. Because of this, we need to keep around the `std::numeric_limits` version in enum expressions until the switch to c++11. Fixes #2148

* First part of a big refactoring of alignment control to enable the handling ↵Gravatar Gael Guennebaud2015-08-06
| | | | | | | | | of arbitrarily aligned buffers. It includes: - AlignedBit flag is deprecated. Alignment is now specified by the evaluator through the 'Alignment' enum, e.g., evaluator<Xpr>::Alignment. Its value is in Bytes. - Add several enums to specify alignment: Aligned8, Aligned16, Aligned32, Aligned64, Aligned128. AlignedMax corresponds to EIGEN_MAX_ALIGN_BYTES. Such enums are used to define the above Alignment value, and as the 'Options' template parameter of Map<> and Ref<>. - The Aligned enum is now deprecated. It is now an alias for Aligned16. - Currently, traits<Matrix<>>, traits<Array<>>, traits<Ref<>>, traits<Map<>>, and traits<Block<>> also expose the Alignment enum.
