[julia-users] Re: what name would you give to the functional 'complement' of trunc()?

I think stretch was a pretty good suggestion, actually. trunc as in “truncate” makes sense for taking 3.14 -> 3 and -2.718 -> -2; you quite literally truncate the decimal representation of the number by chopping off the decimals. I could imagine the opposite, 3.14 -> 4 and -2.718 -> -3, as

Is that code in a function? (It should be.) Also, one of your variable names changed to `counter1s`. Suspect a type instability. On Mar 12, 2016 4:12 AM, "Tim Loderhose" wrote: > I tried around with that a bit, but then it gets much worse: From ~1s to > ~6s, allocation as

Re: [julia-users] Re: Mmap allocation question

It's better to have code which actually runs in the post. In any case, the allocations at the `for` lines is suspicious - the for should basically only allocate a counter. Are there any global variables? Is `counter1` or `counter2` or `dims` global? Globals are always a good source of confusion

Re: [julia-users] Re: Mmap allocation question

Cool, Ill try that out later! I was wondering about that, but obviously I wasn't able to default dims::Array{Int64,1} = 0. How do I make sure it returns a definite type? I know that it should always be an Array{UInt64,1}. I added the code of mdhcounters to the gist. Thanks for the input! On

Re: [julia-users] Re: Mmap allocation question

Yep, `peCounters`, `paCounters` and `dims` are not type-stable. They are one type by their default values and then assigned another. Perhaps rename the default parameters, and copy them to `peCounters`, `paCounters` and `dims` only if they are set to something other than `0`. Also,

x = trunc(fp) yields fp rounded towards zero to the closest integer valued float. What name would you give to the complementary function, rounding away from zero to the closest integer valued float? stretch(fp) = signbit(fp) ? floor(fp) : ceil(fp) # abs(trunc(fp) - stretch(fp)) is 0.0 when

I have been adding more tests to the MixedModels package and encountered a peculiar situation where, AFAICS, a test should produce one type of failure and it doesn't. It fails at a later point but I can't see how it gets there. To reproduce, check out a copy of the MixedModels master branch.
