From http://en.wikipedia.org/wiki/Arithmetic_overflow:
the condition that occurs when a calculation produces a result that is greater in magnitude than that which a given register or storage location can store or represent.
So, for instance:
uint32_t x = 1UL << 31;x *= 2; // Overflow!Note that as @R mentions in a comment below, the C standard suggests:
A computation involving unsigned operands can never overflow, because a result that cannot be represented by the resulting unsigned integer type is reduced modulo the number ...
Content Under CC-BY-SA license What are arithmetic underflow and overflow in C?
Jun 15, 2011 · The situation where an integer outside the allowed range requires more bits than can be stored is called an overflow. Similarly, with real numbers, an exponent that is too small to be stored causes an underflow.

Overflow and Underflow in Java - Baeldung
- In this tutorial, we’ll look at the overflow and underflow of numerical data types in Java. We won’t dive deeper into the more theoretical aspects — we’ll just focus on when it happens in Java. First, we’ll look at integer data types, then at floating-point data types. For both, we’ll also see how we can detect when over- or underflow occurs.
