Sap Easy Expert

Hi Experts ,

I am facing a issue when I use easy expert to change temperature value for  a value assignment .

When I try to change the characterisitic temperature value to -32 deg using easy expert , the values gets updated as -31.9 deg .This happens only for negative values .

If I try to update -32.1 it gets updated as -32 degrees . if we enter the value directly in specification without using easy expert it is working fine.

Can you please clarify the reason fo the issue

Thanks
