e55182ac09 Get rid of initialization logic for blueNorm by making the computed constants static const or constexpr. 
Move macro definition EIGEN_CONSTEXPR to Core and make all methods in NumTraits constexpr when EIGEN_HASH_CONSTEXPR is 1.

Issue with mpreal and std::numeric_limits::digits

511810797e Issue with mpreal and std::numeric_limits, i.e. digits is not a constant. Added a digits() traits in NumTraits with fallback to static constant. Specialization for mpreal added in MPRealSupport. 2017-03-24 17:45:56 +01:00

76faf4a965 Introduce a NumTraits<T>::Literal type to be used for literals, and 
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)

6afea46838 Add infinity() support to numext::numeric_limits, use it in lgamma. 
This makes the infinity access a __device__ function, removing
nvcc warnings.

77ff3386b7 Refactoring of the cost model: 
- 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)

a09cfe650f std::numeric_limits doesn't work reliably on CUDA devices. Use our own definition of numeric_limit<T>::max() and numeric_limit<T>::min() instead of the stl ones. 2015-08-21 16:01:40 -07:00

324e7e8fc9 Removed the deprecated EIGEN2_SUPPORT, as previously announced. A compilation error is raised, if this compile-switch is defined. The documentation references to the corresponding pages from Eigen3.2 now. Also, the Eigen2 testsuite has been removed. 2014-07-01 16:58:11 +02:00

96f08213f7 big eigen2support fix, aimed at users who relied on internal eigen2 stuff: now we dont need customizations in test/eigen2/main.h anymore. 
These tests already build:
eigen2_basicstuff
eigen2_adjoint
eigen2_linearstructure
eigen2_prec_inverse_4x4

7bc8e3ac09 Initial fixes for bug #85. 
Renamed meta_{true|false} to {true|false}_type, meta_if to conditional, is_same_type to is_same, un{ref|pointer|const} to remove_{reference|pointer|const} and makeconst to add_const.
Changed boolean type 'ret' member to 'value'.
Changed 'ret' members refering to types to 'type'.
Adapted all code occurences.

7d72d4f3c7 Bug fix for NumTraits<T>::lowest() . 
std::numeric_limits<T>::min() is the lowest *positive* normalized number
for floating point types.
This fixes the test failure for geo_alignedbox8 for me.

e277586958 Complete rework of global math functions and NumTraits. 
* Now completely generic so all standard integer types (like char...) are supported.
** add unit test for that (integer_types).
* NumTraits does no longer inherit numeric_limits
* All math functions are now templated
* Better guard (static asserts) against using certain math functions on integer types.
