overflowDetected

overflowDetected is a flag or status indicator used in software and hardware to signal that an operation has exceeded the allowable range of a data type or violated memory bounds. It can be a boolean variable, a status bit in a processor’s status register, or a return value from a safe library or function. The concept is common across programming languages and computing environments.

In arithmetic, overflow occurs when the result of an operation cannot be represented within the chosen numeric width. For signed integers, overflow can be detected by analyzing operand signs and the sign of the result (for example, in two’s complement, adding two positive numbers that yield a negative result indicates overflow). For unsigned integers, overflow wraps around modulo the base, and detection often requires separate range checks or built-in overflow intrinsics.

Overflow can also arise in memory operations when writing data beyond allocated buffers. In this context, overflowDetected typically indicates a buffer overflow risk, which can lead to security vulnerabilities such as memory corruption or code execution exploits. Detection methods include explicit bounds checks, canaries, and bounds-safe libraries.

In floating-point arithmetic, overflow refers to results that exceed the representable range, often yielding infinity and triggering the floating-point status flag for overflow. Some environments raise exceptions or alarms when overflowDetected is true, enabling error handling or fallback behavior.

Practically, overflowDetected is used to enforce safety, correctness, and reliability. Languages and libraries provide mechanisms to detect and respond to overflow, including runtime checks, wider arithmetic, or alternative algorithms to prevent data loss and security flaws.
