Detailed Description

template<typename tRes>
struct ScMatrix::IterateResultMultiple< tRes >

When adding all numerical matrix elements for a scalar result such as summation, the interpreter wants to separate the first non-zero value with the rest of the summed values.

This is necessary for better numerical stability, unless we sort all by absolute values before summing (not really an option) or use another algorithm, e.g. Kahan's summation algorithm, https://en.wikipedia.org/wiki/Kahan_summation_algorithm
