The various order of parametric continuity can be described as follows:<ref>{{cite web |first=Michiel |last=van de Panne |url=https://www.cs.helsinki.fi/group/goa/mallinnus/curves/curves.html |title=Parametric Curves |work=Fall 1996 Online Notes |date=1996 |publisher=University of Toronto, Canada |access-date=2019-09-01 |archive-date=2020-11-26 |archive-url=https://web.archive.org/web/20201126212511/https://www.cs.helsinki.fi/group/goa/mallinnus/curves/curves.html |url-status=live }}</ref>
* <math>C^0</math>: zeroth derivative is continuous (curves are continuous)
* <math>C^1</math>: zeroth and first derivatives are continuous
* <math>C^2</math>: zeroth, first and second derivatives are continuous
* <math>C^n</math>: 0-th through <math>n</math>-th derivatives are continuous
