Method Details

### __init__ (self, x, *cs) (Constructor) |
New Fhorner evaluation of the polynomial sum(cs[i] * x**i for i=0..len(cs)). Arguments: `x` - Polynomial argument (`scalar`). `cs` - Polynomial coeffients (`scalar`[]). Raises: `OverflowError` - Partial `2sum` overflow. `TypeError` - Non-scalar `x`. `ValueError` - Non-finite `x`. Overrides: object.__init__ See Also: Function fhorner and methods Fsum.fadd and Fsum.fmul.
