Talk:Angle difference between two bearings

From Rosetta Code

In the first example, are we trying to find (b2 - b1) where b2 = 45 and b1 = 20? Isn’t b2-b1 20? (not -20 like everyone has returned?) --Tim-brown (talk) 11:28, 19 December 2016 (UTC)

Not everyone.   Out of seven solutions (eight outputs), only one showed a negative value for the first example.
I assume you meant 25, not 20.   -- Gerard Schildberger (talk) 14:41, 19 December 2016 (UTC)
The Racket is mine! And the program did better with this tricky bit of arithmetic than I did. --Tim-brown (talk) 18:08, 19 December 2016 (UTC)
