0E-12 value

Hi Guys

I'm using a rounding script for importing data from SAP to HFM with FDMEE or to load from a HFM Application to another HFM application.

The rounding works fine, however when having for example a Value of 719.21 and a reclass booking of -719.21 on a account which is mapped to a target account, which is newly blocked for input; it rounds the source values to 719.00 and -719.00 respectively.

So far so good.

But when trying to load now with FDMEE, it generates a Intersection Validation as it show that it tries to load a value of 0E-12 to the now blocked account. I know that to go around this, I just changed the account mapping to ignore, but would want to know, why it is still generating this 0E-12 value, when normally it should net to zero, and therefore anyway should be ignored by FDMEE?
