I have been looking for a Julia equivalent of Python’s `fsum`

and have thus far been unable to find one. Is there an implementation already available? If not I will write my own and put it on Github for others to use.

**From the Python docs:**

`math.fsum`

( *iterable* )

*Return an accurate floating point sum of values in the iterable. Avoids loss of precision by tracking multiple intermediate partial sums:*

*The algorithm’s accuracy depends on IEEE-754 arithmetic guarantees and the typical case where the rounding mode is half-even. On some non-Windows builds, the underlying C library uses extended precision addition and may occasionally double-round an intermediate sum causing it to be off in its least significant bit.*

*For further discussion and two alternative approaches, see the ASPN cookbook recipes for accurate floating point summation.*
