Method Details

### __init__ (self, x, *cs, **name) (Constructor) |
New Fpolynomial evaluation of the polynomial sum(cs[i] * x**i for i=0..len(cs)). Arguments: `x` - Polynomial argument (`scalar`). `cs` - Polynomial coeffients (`scalar`s), all positional. `name` - Optional name (`str`). Raises: `OverflowError` - Partial `2sum` overflow. `TypeError` - Non-scalar `x`. `ValueError` - Non-finite `x`. Overrides: object.__init__ See Also: Function fpolynomial and method Fsum.fadd.
