(tol=0)[源代码]¶ Remove trailing coefficients
Remove trailing 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 series instance is returned with the new coefficients. The current instance remains unchanged.Parameters:  tol : nonnegative number.
All trailing coefficients less than tol will be removed.
Returns:  new_series : series
Contains the new set of coefficients.
