float- arithmatic

[Teajl Shah]

I tried following code and expected that the output would be 3.0f instead it is 3.0.Does it mean that float addition gives result of type double
float f=1.0f;
float h=2.0f;
float d=f+h;
System.out.println("The value of float addition is " + d);

Java considers a floating point number to be a double, unless it has suffix of an 'f' or 'F' charecter. Since you used that suffix the answer is given in float type.

My qs is :why the output is not 3.0f?

[summer_gsr]

I taught you were asking whether the result was given in a double format? Iam just a beginner in java so I don't know why but for discussion , I think the reason is that just because the variables h and f were defined with a suffix does'nt mean that the answer should be printed out as 3.0f. It just means that it is defined as a float type insead of double. Try to print the variable h the output will be 2.0 and not 2.0f.

Hi Teaji
Your doubt is absolutely right, but the problem is with Java.
Java follows certains rules when you try to define floating point numbers. While processing the floating point values Java does internal conversion. For full details on how does this conversion
, here is the link http://java.sun.com/docs/books/jls/html/3.doc.html#230798

Consider the following example Tejal(I believe this to be a better spelling of your name then Teajl-correct me if I am worng)
and it will be clear to you that the value d is still a float.As explicit casting is needed at line A
Hope this helps
class Ash
{
public static void main(String args[]){
int f=1;
float h=2;
float d=f+h;
System.out.println("The value of float addition is " + d);
double f=5;
float e=d+f; //A
}
}
