Julia | Error with Array Length when It Contains Division

I have a problem in Julia, when the array length is variable and contains a division.

For example

length_of_array = n * (n + 1) / 2

array = Array{Float64,1}(length_of_array)

It returns an error related to "convert".

Thank you for your time.

You can only use integers to index into arrays. Division, /, always returns floats, hence the error. Instead of /, use the div function. You can also use the unicode operator, ÷, like this

length_of_array = (n * (n + 1)) ÷ 2
