Make Prelude.signum handle -0.0 correctly (#7858)
Summary:
Make the `Float` and `Double` implementations of `signum` handle -0.0
correctly per IEEE-754.
This, together with "Make Prelude.abs handle -0.0 correctly (#7858)",
fixes Trac #7858.
Depends on D145
Signed-off-by: Alexander Berntsen <alexander@plaimi.net>
Test Plan:
signum of (-0.0) should be (-0.0) not 0.0.
Test program:
main =
putStrLn $ p ++ " " ++ n
where
f = show . signum
p = f (-0.0 :: Double)
n = f (0.0 :: Double)
