WebArithmetic operations have a potential to run into a condition known as overflow.. Overflow occurs with respect to the size of the data type that must accommodate the result..

A signed integral type and its unsigned counterpart are always the same size, but they differ in how the bit pattern is interpreted for value transformation. The following code example demonstrates what happens when the same bit pattern is interpreted as a signed value and as an unsigned value.
