Amazing Bug in Google Calculator

Here is an experiment of Adhoc Test done with Google Calculator.
Try these.. Go to google site.
Enter this value : 0.00000000000000000001f
It gives output : 0.00000000000000000001 degrees Fahrenheit = -17.7777778 degrees Celsius

Now start reducing number of zeroes in this. And start getting values of conversion.
I tried this at ultimatum.
0.1f
It gave output : 0.1 degrees Fahrenheit = -17.7222222 degrees Celsius

See It’s still same… Isn’t it amazing. Bug still exists from Beta Version of Google Product.
Now last amazing part :
Put "1f + 1f" in google search. We all know it should become 2f or -35.44444444444 degrees Celsius
But see how simple calculation is displayed in google.
It gave output : (1 degree Fahrenheit) + (1 degree Fahrenheit) = 238.705556 degrees Celsius

Just a thought : No matter where you are, either in a pond or an ocean, if you can think you can do it, yes you can even find something in an ocean "like Google".

Happy Testing.
