about amplus

Can circulus amplus mean “exactly circular form”, other than “a large circle” ?
For amplus,

amplus originally means “full all around”, according to L&S.

I don’t see an example anywhere where it clearly means that.
Ego equidem istius sensûs exemplum invenire non possum.

I don’t see, too, in L&S.
How do you think ?
Exactly circular form is possible, or impossible, according to L&S ?

Perhaps it’s not impossible, as you say, but mathematicians tend to say “circulus perfectus”.
Non impossibile, ut dicis, at saepiùs solent dicere mathematici perfectum esse circulum.

Thank you. :slight_smile:
