What does Infinity mean?

Answer 1

Did you divide by zero?

When you divide by zero ...

In case of double/float division, the output is Infinity. The basic reason behind it is that it implements the floating point arithmetic algorithm, which specifies special values like “Not a number” OR “infinity” for “divided by zero cases” as per IEEE 754 standards.

In case of integer division, it throws ArithmeticException.

This, will print "Infinity"

    double p = 1; 
    System.out.println(p/0);
