- Polynomial. trim ( tol = 0 ) ¶
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
. A new series instance is returned with the new coefficients. The current instance remains unchanged.
- tol non-negative number.
All trailing coefficients less than tol will be removed.
- new_series series
New instance of series with trimmed coefficients.
