> Currently native redis appears to be able to apply INCRBYFLOAT on values that are below the max of unsigned long long (18446744073709551615). However, since we're treating numbers as \{{double}}s we can lose precision for very large values. For example:
>
> {{set val 18446744073709551614
> incrbyfloat val 1}}
> incorrectly returns {{18446744073709552000}}
> Native redis produces a correct result.
