Angles (geometric), normalization and conversion

Normalize degree angles and convert between degrees and radians for fixed sample values.

Edit the source, then Run. Checks start after your first Run. Ctrl/⌘ + Enter runs; Tab indents. Preview services use sample data and never contact a real service.
