Partial spaces -- round up or round down

I have a calculation for preferred spaces that falls less than .5 of a space (7.35spaces = 5% of 147). In most land use or permit calculations there is specific language indicating that one can round down in these cases. Therefore, 7 spaces would be sufficient to achieve the amount. However, in LOL when I put 7 spaces into the template, the template indicates that I have not documented the amount of spaces required in order to comply. I don't find any language in the guidebook or credit language that indicates that the amount must be GREATER than 5% or... no less than 5% of total parking. Therefore, I'm thinking that rounding down on partial spaces would be allowed. So how should we deal with partial parking spaces when calculating total required?
