I am using the function below to convert a continuous variable to a binned value. Sometimes a value other than zero is passed through the query. For example -.5 result value is passed to the query result. The basic of the query is below.
select
incentivebin(wac, rate, .25)
from
my_table
where incentivebin(was, rate, .25) = 0
I have checked the function works correctly and the raw values match those values expected from simple subtraction and are in the correct bin. I am not sure why some values would be allowed through the query. Any ideas would be appreciated.
Best,
Glenn
