* Fix c++20 warnings about using enums in arithmetic expressions.Gravatar Rasmus Munk Larsen2021-06-10

* 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

* Add support for Armv8.2-a __fp16Gravatar David Tellenbach2020-10-28
| | | | | | | | | | | | | | | Armv8.2-a provides a native half-precision floating point (__fp16 aka. float16_t). This patch introduces * __fp16 as underlying type of Eigen::half if this type is available * the packet types Packet4hf and Packet8hf representing float16x4_t and float16x8_t respectively * packet-math for the above packets with corresponding scalar type Eigen::half The packet-math functionality has been implemented by Ashutosh Sharma <ashutosh.sharma@amperecomputing.com>. This closes #1940.

* Introduce a NumTraits<T>::Literal type to be used for literals, andGravatar Gael Guennebaud2016-06-23
| | | | | | | improve mixing type support in operations between arrays and scalars: - 2 * ArrayXcf is now optimized in the sense that the integer 2 is properly promoted to a float instead of a complex<float> (fix a regression) - 2.1 * ArrayXi is now forbiden (previously, 2.1 was converted to 2) - This mechanism should be applicable to any custom scalar type, assuming NumTraits<T>::Literal is properly defined (it defaults to T)

* Refactoring of the cost model:Gravatar Gael Guennebaud2015-10-28
| | | | | | | | | | | - Dynamic is now an invalid value - introduce a HugeCost constant to be used for runtime-cost values or arbitrarily huge cost - add sanity checks for cost values: must be >=0 and not too large This change provides several benefits: - it fixes shortcoming is some cost computation where the Dynamic case was not properly handled. - it simplifies cost computation logic, and should avoid future similar shortcomings. - it allows to distinguish between different level of dynamic/huge/infinite cost - it should enable further simplifications in the computation of costs (save compilation time)

* Complete rework of global math functions and NumTraits.Gravatar Benoit Jacob2010-04-28
