(tol=0)¶ Remove small leading coefficients
Remove leading coefficients until a coefficient is reached whose absolute value greater than tol or the beginning of the series is reached. If all the coefficients would be removed the series is set to
[0]
. A new Polynomial instance is returned with the new coefficients. The current instance remains unchanged.Parameters: tol : non-negative number.
All trailing coefficients less than tol will be removed.
Returns: new_instance : Polynomial
Contains the new set of coefficients.
