Numeric overflow
Reports expressions that overflow during computation. Usually, this happens by accident and indicates a bug. For example, a wrong type is used or a shift should be done in an opposite direction .
Examples:
float a = 1.0f/0.0f;
long b = 30 * 24 * 60 * 60 * 1000;
long c = 1000L << 62;
