An infinite number is a number that has no end and is not measurable. We can have infinite numbers that are positive and negative. These numbers are called positive infinity and negative infinity. We can check if a float value is infinite or not by using the infinite? method.
fl_num.infinite?
This method takes no parameters. They are only invoked on a float object or value.
The value returned is 1, -1, or nil. 1 is returned if it is infinity or positive infinity. -1 is returned if it is negative infinity. Otherwise, nil is returned.

infinite? method to determine whether the float values are infinite or not. We then print the results on the console.
