What is the biggest "no-floating" integer that can be stored in an IEEE 754 double type without losing precision?
As far as I know floating point values are of the form n * 2^e, with float range being n = -(2^23-1) - (2^23-1), and e = -126 - 127,
Of course one should never compare floating point values that result from a calculation for equality, but always use a small tolerance, e.g.:
I know this is wrong and gcc will give you a warning about it, but why does it work (i.e. the numbers are printed correctly, with some rounding difference)?
