Overflow occurs when a value exceeds its maximum representable range i.e., when incremented beyond it's representable range, the value wraps around the next starting loop (start from 0) i.e. 65535 + 2 = 0 #Solidity #OverflowAndUnderflow
while underflow happens when a value goes below its minimum representable range i.e., when decreased beyond it's representable range, the value wraps around the next starting loop (start from last unsigned integer). i.e. 0 - 2 = 65534 #Solidity #OverflowAndUnderflow
TL;DR: Integer overflow/underflow occurs when an arithmetic operations are performed and the result/outcome is outside the range. Use @OpenZeppelin SafeMath.sol prevent such issues. #Solidity #OverflowAndUnderflow
uint16 can holds the integer value between 0 - 2^256 -1 i.e. 65536. #Solidity #OverflowAndUnderflow
