Guardian - Guardian's Armor

[Lance Schantz 455]

Even when you are struck, your armor protects you from some harm. While wearing medium or heavy armor, you gain resistance to physical damage equal to 1 + half your level. In addition, you can rest normally while wearing medium and heavy armor.

My question is, is your half you level rounded down, so at level 1 you have resistance 1, that seems to be what the general thought is from my search, but I know spells and such on a save are half damage round down to a minimum of 1, which would give you resistance 2 if that applied with that thought process.

Can someone please clarify this for me.

Rounding

You may need to calculate a fraction of a value, like halving damage. Always round down unless otherwise specified. For example, if a spell deals 7 damage and a creature takes half damage from it, that creature takes 3 damage.
