llGetInventoryNumber( INVENTORY_ALL ) - 2?

[SeeAirAhh Josephina]

I'm trying to substract 2 from total inventory, the full string is items_contained = llGetInventoryNumber( INVENTORY_ALL ); so if I wanted to subtract 2 from the inventory would that be like  llGetInventoryNumber( INVENTORY_ALL ) - 2 or?

'doh' should have tried it before posting, I answered my own question lol

Better formatted would be:

integer total_inv = llGetInventoryNumber(INVENTORY_ALL);
integer new_number = total_inv - 2;

Alternatively assuming you want to exclude something specific from your count you could do:
integer i;
integer count = 0;
for(i = 0; i < total_inv ; i++){
   string inv_name = llGetInventoryName(INVENTORY_ALL, i); 
   if(inv_name != "blabla" && inv_name != "somename"){
      count++;
   }
}
llSay(0, (string)count);

It  really depends on the use-case. Looping through all the items in the prims inventory and checking them against multiple strings might be unnecessarily wasteful if you've already somehow confirmed the existence of those two things earlier in the code.
