# Fix SUM aggregate function for mixed types
Fixes #2133
The SUM aggregate function was returning incorrect results when
processing tables with mixed numeric and non-numeric values. According
to SQLite documentation:
> "If any input to sum() is neither an integer nor a NULL, then sum()
returns a floating point value"
[*](https://sqlite.org/lang_aggfunc.html)
Now both SQLite and Turso yield the same output of 44.0.

I modified `Sum` to increment only for numeric values, skipping non-
numeric values. However, if we have mixed numeric values or non-numeric
values, we return a float output. Added a flag to keep track of it.
as pointed out by @FHaggs , If there are no non-NULL input rows then
sum() returns NULL but total() returns 0.0. I decided to include it in
this PR as well. Empty was such a natural test case.
