In Quality Control, when we are inserting Test results in Maintain Tests, it hides 0 after inserting 0 and after inserting 0.5. It shows .5 instead of 0.5. Is there any way to change it.

Another is how to take samples less than 1% or through any formula.

I think this is part of the display format for the field / domain you are using... it is showing ZZZZVD99 instead of ZZZ9VD99...
