Examples of errors detected by the V6020 diagnostic

V6020. Division or mod division by zero.


Apache Hive

public static long divideUnsignedLong(long dividend, long divisor) {
  if (divisor < 0L) {
    /*some comments*/
    return (compareUnsignedLong(dividend, divisor)) < 0 ? 0L : 1L;
  }

  if (dividend >= 0) { // Both inputs non-negative
    return dividend / divisor;                     // <=
