It's overflow. Underflow is when a floating point value is too close to zero.

>From <https://en.wikipedia.org/wiki/Integer_overflow>: "an integer overflow
occurs when an arithmetic operation attempts to create a numeric value that is outside of the range that can be represented with a given number of digits – either higher than the maximum or lower than the minimum representable value."

>From <https://en.wikipedia.org/wiki/Arithmetic_underflow>: "Storing values that
are too low in an integer variable (e.g., attempting to store −1 in an unsigned integer) is properly referred to as integer overflow, or more broadly, integer wraparound."

Could call it "wraparound" in the error message to avoid confusion.

Staying in standard terminology is good enough IMO. My misunderstanding.
