I was playing around with type declarations and came across an
counterintuitive result. I'm not sure if this is the intended behavior or
not, but it certainly surprised me.
Consider the functions
*function f(x)*
*y::Int*
*y=x*2.0*
*end*
*function g(x)*
*y::Int*
*y=x*2.0*
*y*
*end*
*julia> **f(1),g(1)*
*(2.0,2)*
I expected them to behave identically, always returning an Int. But clearly
f returns a Float64.
It seems like in the presence of the type delaration y=x*2.0 is interpreted
as
temp=x*2.0
y=Int(temp)
temp
is that right?
