i bit confused how rounding in python works. please explain why python behaves this? example: >>> round(0.05,1) # makes sense 0.1 >>> round(0.15,1) # doesn't make sense! why result not 0.2? 0.1 and same for: >>> round(0.25,1) # makes sense 0.3 >>> round(0.35,1) # in opinion, should 0.4 evaluates 0.3 0.3 edit: in general, there possibility python rounds down instead of rounding up. understand "abnormal" thing can happen python rounds down? or may rounded "abnormally" due how stored? (i haven't found case python rounded when expected round down) this design. pythons' documentation : the behavior of round() floats can surprising: example, round(2.675, 2) gives 2.67 instead of expected 2.68. this not bug : it’s result of fact decimal fractions can’t represented float.

i create ratio between 0-1 of how "colorful" color is, colorful mean: black colors have ratio 0 (no light) white colors have ratio 0 (no saturation) a saturated / lighted color has ratio 1 i tried converting color hsv colorspace , calculating ratio as: ratio = (color.value / 100) * (color.saturation / 100) this works somewhat, feels curve wrong, example hsv(hue=0, saturation=80, value=80) only gives ratio of 0.64 looks close saturated / lighted color. maybe need somehow create "ease-out" on values? thought taking human perception of colors account aswell (using lab or yuv colorspaces) dont think needed here, might wrong. the definition of saturation hsv not want, because not compensate lightness of color. from the wikipedia article on colorfulness : [perceived saturation] proportion of pure chromatic color in total color sensation. where s ab saturation, l* lightness , c* ab chroma of color. this definition u...

when inserting multiple rows in table, there guarantee go in in order specify? instance, take following: declare @blah table ( id int identity(1, 1), name varchar(100) not null ); insert @blah (name) values('timmy'), ('jonny'), ('sally'); select * @blah is there guarantee sally have higher primary key timmy ? the similar question asked before. you can specify order by in insert . if that, order in identity values generated guaranteed match specified order by in insert . using example: declare @blah table ( id int identity(1, 1) not null, name varchar(100) not null ); insert @blah (name) select t.name ( values ('timmy'), ('jonny'), ('sally') ) t(name) order t.name; select t.id ,t.name @blah t order t.id; the result is: +----+-------+ | id | name | +----+-------+ | 1 | jonny | | 2 | sally | | 3 | timmy | +----+-------+ tha...

i have input users regarding skills. have table skills has id primary key. in other table storing user id , skill id many many relationship. problem how know skill entered user in skills table? because have put id of skill in many many relationship table. run each time select statement or there efficient solution available? thanks, how know skill entered user in skills table? in concurrent environment, there no way know that. if select, tells whether row existed @ time of select execution - doesn't tell whether row exists now . example, if select returned empty result, concurrent transaction might have inserted row within few milliseconds took receive select result. so either drastic reduction in concurrency (e.g. through table locks), or learn live it... when insert needed i'd recommend attempt insert (without select) , ignore possible primary key violation 1 . if did separate select , insert steps, you'd still have prepared pk violations, since...

there was, writing function takes value input, calls function on input, , if result of just x , should return x ; otherwise, should return original input. in other words, function (that didn't know call): foo :: (a -> maybe a) -> -> foo f x = frommaybe x (f x) since seems general-purpose function, wondered if wasn't defined, i asked on twitter , , chris allen replied it's ap frommaybe . that sounded promising, fired ghci , started experimenting: prelude control.monad data.maybe> :type ap ap :: monad m => m (a -> b) -> m -> m b prelude control.monad data.maybe> :type frommaybe frommaybe :: -> maybe -> prelude control.monad data.maybe> :type ap frommaybe ap frommaybe :: (b -> maybe b) -> b -> b the type of ap frommaybe looks correct, , couple of experiments seem indicate has desired behaviour well. but how work? the frommaybe function seems clear me, , in isolation, think understand ap - @ least in context o...
