object --+ | Fsum
Precision floating point summation similar to standard Python function math.fsum.
Unlike math.fsum, this class accumulates the values to be added incrementally and provides intermediate, precision summations. Accumulation can continue after intermediate summations.
Exception and non-finite handling differs from math.fsum.
See Also: Hettinger, Klein, Kahan, Python 2.6+ file Modules/mathmodule.c and the issue log Full precision summation.
