Can someone explain me why is this happening:

1+2+DBL_MAX-DBL_MIN = 0 and 1+DBL_MAX-DBL_MIN+2=3?

because in the float point arithmetics a + b + c does not have to be equal to c + b + a and you have the UB here as well - so any result is good. – 0___________ Oct 07 '17 at 18:41
What does it mean UB? – Ninalol Oct 07 '17 at 19:59
