Method Details

### __init__ (self, a, *b) (Constructor) |
New Fdot precision dot product sum(a[i] * b[i] for i=0..len(a)). Arguments: `a` - List, sequence, tuple, etc. (`scalar`s). `b` - All positional arguments (`scalar`s). Raises: `OverflowError` - Partial `2sum` overflow. `LenError` - Unequal `len(a)` and `len(b)`. Overrides: object.__init__ See Also: Function fdot and method Fsum.fadd.
