Strange behaviour of a variable :/

[Loriel]

client.attrib.hp is 9999, here.

NPC Code:

---

hp = strtofloat(#s(client.attrib.hp));

setplayerprop #c,#v(hp) #v(strtofloat(#s(client.attrib.hp)));

---

Result: "1807 9999"
Are "hp"-variables limited somehow?
The hp thingie is acting as if I did hp = strtofloat(#s(client.attrib.hp))%2048;

Strangely, the mp are working fine, though using the very same thingie.
