Time for action – Using floats

Floats are used when we need something that doesn't have nice neat values, like how far away something is or how accurate a weapon is. They're declared the same way as our bools and ints, so let's make one now.

1. Replace our int declaration with this:

   var float DistanceToGo;

2. Floats have a default value of 0.0. Let's change our PostBeginPlay function to check this.

   function PostBeginPlay()
   {
      'log("Distance to go:" @ DistanceToGo);
   }

3. Compile and test, and our log should look like this:

   [0007.61] ScriptLog: Distance to go: 0.0000

4. We can see that unlike ints, floats will log with a decimal place. Let's see if we can change the value. Add this line to the beginning of our PostBeginPlay function:

   DistanceToGo = 0.123;

5. Compile and test, and we should see the fraction show up in the log:

   [0007.68] ScriptLog: Distance to go: 0.123

6. Let's see what happens when we use the same line we did for our int. Change the line to this:

   DistanceToGo = 10 / 3;

7. Compile and test, and our log should...
