Overflow

/ˈoʊ-vər-ˌfloʊ/

noun — “what happens when a number tries to be bigger than the container pretending to hold it.”

Overflow is a condition in computing where a value exceeds the maximum representable range of a fixed-size numeric type. It occurs when an operation produces a result that cannot be stored within the allocated number of bits, especially in integer arithmetic, though it can also appear in floating-point systems in a different form.
