我仍在学习 Julia 语言,但出现此错误。我正在编写一个蚊子种群模型,我正在尝试运行我的主要功能 100 次。此主函数使用许多其他函数来计算子种群水平。
# Importing KNMI data
xf = XLSX.readxlsx("C:/Scriptie_mosquitoes/knmi_csv.xlsx")
sh = xf["knmi_csv"]
temperature = sh["B3:B368"]
precip = sh["F3:F368"]
subpopulation_amount = 100
imat_list1 = zeros(100,length(temperature))
imat_list = Array{Float64}(imat_list1)
adul_list1 = zeros(100,length(temperature))
adul_list = Array{Float64}(adul_list1)
egg_list1 = zeros(100,length(temperature))
egg_list = Array{Float64}(egg_list1)
diaegg_list1 = zeros(100,length(temperature))
diaegg_list = Array{Float64}(diaegg_list1)
imat_list[1] = 100.0
adul_list[1] = 1000.0
egg_list[1] = 100.0
diaegg_list[1] = 100.0
for counter = 1:1:subpopulation_amount
u = Distributions.Normal()
temp_change = rand(u)
tempa = temperature .+ temp_change
println(tempa)
e = Distributions.Normal()
precip_change = rand(e)
println("hallo", precip_change)
println(counter,tempa,precip,precip_change)
main(counter,tempa::Array{Float64,2},precip::Array{Any,2},precip_change::Float64,imat_list::Array{Float64,2},adul_list::Array{Float64,2},egg_list::Array{Float64,2},diaegg_list::Array{Float64,2})
end
但是我得到了这个错误,我试图用所有的 Float64 stuf 来修复它。不幸的是,我不工作。我希望你们中的一些人看到了这个问题,或者可以帮助我理解错误信息。

最佳答案
您可以查看 InexactError
的文档。通过输入 ?InexactError
:
help?> InexactError
search: InexactError
InexactError(name::Symbol, T, val)
Cannot exactly convert val to type T in a method of function name.
我认为这很好地解释了它。没有
Int64
表示值 87.39533010546728
.您有多种选择。查看他们的帮助以了解有关他们的更多信息:
julia> trunc(Int, 87.39533010546728)
87
julia> Int(round(87.39533010546728))
87
julia> Int(floor(87.39533010546728))
