*	Revert "Add log2() operator to Eigen"	Rasmus Munk Larsen	2020-12-03
\| \| \| \|	This reverts commit 4d91519a9be061da5d300079fca17dd0b9328050.

*	Bug #1785: Introduce numext::rint.	Ilya Tokar	2020-01-07
\| \| \| \| \| \|	This provides a new op that matches std::rint and previous behavior of pround. Also adds corresponding unsupported/../Tensor op. Performance is the same as e. g. floor (tested SSE/AVX).

\|
*	Generalize expr.pow(scalar), pow(expr,scalar) and pow(scalar,expr).	Gael Guennebaud	2016-06-14
\| \| \| \|	Internal: scalar_pow_op (unary) is removed, and scalar_binary_pow_op is renamed scalar_pow_op.
*	Add TernaryFunctors and the betainc SpecialFunction.	Eugene Brevdo	2016-06-02
\| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \| \|	TernaryFunctors and their executors allow operations on 3-tuples of inputs. API fully implemented for Arrays and Tensors based on binary functors. Ported the cephes betainc function (regularized incomplete beta integral) to Eigen, with support for CPU and GPU, floats, doubles, and half types. Added unit tests in array.cpp and cxx11_tensor_cuda.cu Collapsed revision * Merged helper methods for betainc across floats and doubles. * Added TensorGlobalFunctions with betainc(). Removed betainc() from TensorBase. * Clean up CwiseTernaryOp checks, change igamma_helper to cephes_helper. * betainc: merge incbcf and incbd into incbeta_cfe. and more cleanup. * Update TernaryOp and SpecialFunctions (betainc) based on review comments.
