Is it a Bug in windows calculator ?
Many people think that this is a bug in windows calculator. This is really amazing for a layman. Just write 9 in calculator, then press the square root button and then subtract 3 from it. As per our calculation it should give zero. But it does not give. It gives some fractional value.
Do you also think it is a bug ? If it is so, then change your mind. After reading in many blogs and forums I concluded that this is not a bug. Actually according to the scope of calculator the square root of 9 is not exactly 3 rather it is nearly equal to 3. However if you will calculate Sqrt(9)+3 you will never get fractional values it is because if the answer is coming greater than zero, it does not show you the fractional part which is almost negligible. But if the answer is coming to be zero then it shows you the fractional part although it is negligible.
