This is an attempt to translate an example from K&R C. I am unable to parse the InexactError() the code throws up.
```julia
struct Point
x::Int
y::Int
function Point()
new(0, 0)
end
function Point(i::Union{Int, Float64}, j::Union{Int, Float64})
new(i, j)
end
end
struct Rect
p1::Point
p2::Point
end
screen = Rect(Point(), Point(16.0, 9.0))
middle = Point((screen.p1.x + screen.p2.x)/2, (screen.p1.y + screen.p2.y)/2)
```
middle throws up an InexactError():
```julia
InexactError()
convert(::Type{Int64}, ::Float64) at float.jl:679
Point(::Float64, ::Float64) at KRC.jl:52
```
How do I correct this?

Either change `x` and `y` to be `Float64` or explicitly round using `round((screen.p1.x + screen.p2.x)/2)` or `round(Int, (screen.p1.x + screen.p2.x)/2)`.
```julia
julia> Int(1.2)
ERROR: InexactError()
Stacktrace:
[1] convert(::Type{Int64}, ::Float64) at .\float.jl:679

julia> round(1.2)
1.0
julia> round(Int, 1.2)

julia> Int(1.0)

Got it, my struct definition was wrong. 😐
