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