                 Key: MADLIB-954
                 URL: https://issues.apache.org/jira/browse/MADLIB-954
             Project: Apache MADlib
          Issue Type: Bug

For the function
http://doc.madlib.net/latest/group__grp__summary.html

For a table with the following column:
depdelay             | double precision |

{code:sql}
gpuser=> select madlib.summary('faa.otp_r', 'faa.otp_summary1', 'DepDelay');
{code}

results in the following error:

{code}
ERROR: ZeroDivisionError: float division (plpython.c:4648)
CONTEXT: Traceback (most recent call last):
PL/Python function "summary", line 25, in 
get_distinct, get_quartiles, ntile_array, how_many_mfv, get_estimates)
PL/Python function "summary", line 77, in summary
PL/Python function "summary", line 382, in run
PL/Python function "summary"
{code}

As per PostgreSQL rules, though should be OK.
