Is it positive infinity to negative infinity?
Than how can it fit in into 32 bit and 64
bits?

Hi sanjay,
range of Float and double can be found by running the following program.
--------------------------------------------------------
class MaxMin
{
public static void main(String j[])
{
System.out.println("Max Float :"+Float.MAX_VALUE);
System.out.println("Min Float :"+Float.MIN_VALUE);
System.out.println("Max Double :"+Double.MAX_VALUE);
System.out.println("Min Double :"+Double.MIN_VALUE);
}
}
--------------------------------------------------------
Now POSITIVE_INFINITY and NEGATIVE_INFINITY are two constants defined by Float and double classes which are used to handle overflow and underflow conditions.as soon as it seems that the value assigned to float /double is going to be greater than MAX_VALUE or less than MIN_VALUE then java uses two infinity constants and neatly saves us from an exception.
