                       Fsum2Tuple

2-Tuple `(fsum, residual)` with the precision running `fsum` and the `residual`, the sum of the remaining partials. Each item is either `float` or `int`.

Note: If the `residual is INT0`, the `fsum` is considered to be exact, see method Fsum2Tuple.is_exact.

Instance Methods
is_exact(self) Is this Fsum2Tuple considered to be exact? (`bool`). |
is_integer(self) Is this Fsum2Tuple `integer`? (`bool`). |
