[julia-users] Re: If (in my system) Int is an alias for Int32, then why there is no Float alias for Float32/64?

true; they should, but I guess to comply with the IEEE 754 standard 
http://en.wikipedia.org/wiki/IEEE_754-1985
so you can go for 64 or 32, they could have build in Float to 
detect the cpu arch type but there is a reason for not 
doing so.
