Time for action – Math!

1. As an example, take a look at this code.

   var float Float1, Float2;
   var int Int1;
   
   function PostBeginPlay()
   {
       Float2 = Int1 / Float1;
       'log("Float2:" @ Float2);
   }
   
   defaultproperties
   {
       Int1=5
       Float1=2.0
   }

2. We can divide an int by a float or vice versa, and we get the result we expect:

   [0008.10] ScriptLog: Float2: 2.5000

   However, if we divide an int by an int and assign it to a float, what would we expect the result to be?

3. Let's take a look at this code:

   var float Float1;
   var int Int1, Int2;
   
   function PostBeginPlay()
   {
       Float1 = Int1 / Int2;
       'log("Float1:" @ Float1);
   }
   
   defaultproperties
   {
       Int1=5
       Int2=2
   }

   With that it looks like we'd expect the same result. Let's take a look at the log:

   [0007.66] ScriptLog: Float1: 2.0000

   When dividing ints, the truncating happens before assigning the result, even if it's a float. Depending on what we're doing this may be what we want, but it's good to keep that in mind.
