Gopal Vijayaraghavan commented on HIVE-22315:
---------------------------------------------
{code}
+ public long roundingDivision(long divident, long divisor, long valueHalf) {
+ return ((divident > 0) ^ (divisor > 0)) ?
+ (-Math.abs(divident) - Math.abs(valueHalf) + 1) / Math.abs(divisor) :
+ (Math.abs(divident) + Math.abs(valueHalf) - 1) / Math.abs(divisor);
+ }
{code}
needs some documentation, I know I'm going to forget this by next week.
