HI Vidhya,
as you that both the numbers are double but not float .
you can even check that for integer and short type
why is that when you give a number in short data type range ,the compiler
always infers it to be of type Int?
One of the reasons is that the compiler plays safe.It avoids any runtime
problem that might occur.
for that reasons it follows some conventions:
a integer,short,byte by default is assumed to be integer when you haven't
specified its type.
and ||ly
for floating point numbers
the default is double.(if you haven't specified any type)
ex:
scala> val x:float=20.0
<console>:4: error: type mismatch;
found : Double(20.0)
required: float
val x:float=20.0
scala> val y:Float=10.3f
y: Float = 10.3

Hi all,
While using the scala interpreter i d a doubt. Why is it that 17.8653 is
double and 17.2 is also double. Why cant 17.2 be considered as float?
Reg,
Vidhya
