ApproxEq
Description
Provides a typeclass for for comparing shapes that are approxmately the same size and have the same position in 2-d space.
Synopsis
- class Show s => ApproxEq s
- approxEqual :: ApproxEq s => s -> s -> Float -> Bool
- (=~) :: ApproxEq s => s -> s -> Bool
- assertApproxEqual :: (ApproxEq s, HasCallStack) => s -> s -> Float -> Assertion
- (@?~) :: ApproxEq s => s -> s -> Assertion
Documentation
class Show s => ApproxEq s Source #
Minimal complete definition
approxEqual :: ApproxEq s => s -> s -> Float -> Bool Source #
Are two shapes identical to within a given tolerance?
(=~) :: ApproxEq s => s -> s -> Bool Source #
Are two shapes identical to within a given tolerance? Infix version where epsilon is fixed at 0.0001.
assertApproxEqual :: (ApproxEq s, HasCallStack) => s -> s -> Float -> Assertion Source #
Helpful assertion for testing.
