*	Fix double-promotion warnings	Christoph Hertzberg	2021-02-27
\| \| \| \|	(cherry picked from commit c22c103e932e511e96645186831363585a44b7a3)
*	Some improvements for kissfft from Martin Reinecke(pocketfft author):	Guoqiang QI	2021-02-24
\| \| \| \| \| \|	1.Only computing about half of the factors and use complex conjugate symmetry for the rest instead of all to save time. 2.All twiddles are calculated in double because that gives the maximum achievable precision when doing float transforms. 3.Reducing all angles to the range 0<angle<pi/4 which gives even more precision.
*	Remove vim specific comments to recognoize correct file-type.	David Tellenbach	2021-02-09
\| \| \| \|	As discussed in #2143 we remove editor specific comments.
*	Use std::complex constructor instead of assignment from scalar	Jonathan Liu	2018-06-28
\| \| \| \| \|	Fixes GCC conversion to non-scalar type requested compile error when using boost::multiprecision::cpp_dec_float_50 as scalar type.
*	Fix bug #314:	Gael Guennebaud	2012-11-06
\| \| \| \| \|	- remove most of the metaprogramming kung fu in MathFunctions.h (only keep functions that differs from the std) - remove the overloads for array expression that were in the std namespace
