Significant Figures: Do Instructors Require Them?

[Elbobo]

There isn't really a problem, but I just had a question about sigfigs. My current Physics teacher tells my class that in physics significant figures aren't that important like in chemistry, so we ignore them in our problems and just round to the nearest hundredth.

Do you instructors require significant figures for your students? My textbook uses them, so I have a feeling I should get used to them again.

Probably what they meant was that physics lessons are concerned with how you get the answer not the details of the measuremnt.
In experimental physics - precision, accuracy, experimental error and sig figures are important.
