The problem as I had figure it out that in trunc(Int32, 4.107939275e9) .

The number 4.107939275e9 exceeds the maximum of the type Int32 .

julia> typemax( Int32)
2147483647
julia> 4.107939275e9 > typemax( Int32)
true

i do not know the significant of the number or why we should use it so i cant think of a slon.

Nice to see such quick payback from the new InexactError.

@DrKrar, to fix this someone will have to know a lot more about what you did to trigger this error. Can you post an example that one can copy/paste into the REPL?

[timholy]

Could be the issue fixed in JuliaLang/julia#22644.

to fix this someone will have to know a lot more about what you did to trigger this error.

If this is related to #963, then apparently it is triggered by using Plots for the first time on 32bit architectures in this function

"get an array of tuples of points on a circle with radius `r`"
function partialcircle(start_θ, end_θ, n = 20, r=1)
    Tuple{Float64,Float64}[(r*cos(u),r*sin(u)) for u in linspace(start_θ, end_θ, n)]
end

Is this fixed in JuliaLang/julia#22644 or does it have to be fixed in Plots?

[timholy]

I don't have a 32bit machine, so someone else will have to test. I just merged that PR so anyone running 0.7 can just do a git pull && make.

It seems likely that it's fixed, and the fix should be backported to 0.6.

[DrKrar]

I agree with you @daschw . Dear @timholy thanks for your prompt response. I did not build my instillation of Julia. I will wait to download the Compiled master including this build and report the results.

[DrKrar]

Dear @timholy now all is alright .

[dpo]

Any idea when this will be backported to 0.6? I keep getting this error on Appveyor/Win32, e.g., https://ci.appveyor.com/project/dpo/benchmarkprofiles-jl/build/1.0.31/job/kci9pba13oi3wwyx#L80.
