Data.Primitives.Views.divides behaves odd with negative dividend #4899
Open
Description
Steps to Reproduce
module Issue
import Data.Primitives.Views
divTest : (Integer, Integer) -> (Integer,Integer)
divTest (x, y) with (divides x y)
divTest (x, 0) | DivByZero = (x, 0)
divTest (x@(y * _ + _), y) | DivBy _ = (x, y)
it : Issue.divTest <$> [(-13, 4), (-13, -4)] = [(-13, 4), (-13, -4)]
it = Refl
Expected Behavior
type check passes
Observed Behavior
|
11 | it = Refl
| ~~~~
When checking right hand side of it with expected type
divTest <$> [((-13), 4), ((-13), (-4))] = [((-13), 4), ((-13), (-4))]
Type mismatch between
x = x (Type of Refl)
and
[(-11, 4), (-11, -4)] = [(-13, 4), (-13, -4)] (Expected type)
Specifically:
Type mismatch between
-11
and
-13
