Comment on Tutorial : float vs double data types in Java By Baski

Actually, the given accuracy just barely exceeds what is possible in a float. A float is stored as:  1 sign bit, 23 mantissa bits, 1 sign bit for the exponent, and 7 bits for the exponent value.



Since the largest value that can be stored in 23 bits is 8388608, two consecutive floats in this region are:



8380398/131072 = 63.93736267

8380399/131072 = 63.9373703



Meaning that it can just barely distinguish between 63.93736 and 63.93737, which is still MUCH better than the human eye!
