Newbie-type question: This is true: Float64 <: FloatingPoint
This is false:
Array{Float64} <: Array{FloatingPoint}
Why? I'm perhaps not referring here to the actual code to explain why.
Rather why should this be so?
Let us say I wanted to write a function
function f(a::Array{FloatingPoint})
show(a)
end
And then
#define an array
A=Float64[1.0 2.0; -3.0 -4.0; 5.0 6.0]
#this will fail. Why should it fail?
f(A)
