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
- tolnon-negative number.
All trailing coefficients less than tol will be removed.
- Returns
- new_seriesseries
New instance of series with trimmed coefficients.
