tdf#137679 Use Kahan summation for scmatrix operations
May also want implement Kahan sum in there:
sc/source/core/tool/arraysumSSE2.cxx
sc/source/core/inc/arraysumfunctor.hxx
Under some conditions the sum of a pointer type vector
may be perforemed by arraysumfunctor on NumericCellAccumulator.
arraysumSSE2 implements part of it.
This code has been left unmodified.
Why the test has been modified:
The error was: 238.89000000000001 != 238.89

17 th digit
IEEE 754 double-precision has 53 log10(2) ≈ 15.955 digits.
So it's just noise.
