                         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)
