Interesting, in contrary to C++ it saves the integral part in the 
dummy variable. Doing this I noticed if I try to write a double 
variable in the console it gives me only the integral part. I 
only did it with writeln so far. How can I print out a double 
variable with a precision of 2 for instance? I tried it with 
writefln("%d", d)
It compiles but crashes.
