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 }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?
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.
Two other operators that can be used for simple...

Overview of this book
Unreal Development Kit is the free edition of Unreal Engine—the largest game engine in existence with hundreds of shipped commercial titles. The Unreal Engine is a very powerful tool for game development but with something so complex it's hard to know where to start.This book will teach you how to use the UnrealScript language to create your own games with the Unreal Development Kit by using an example game that you can create and play for yourself. It breaks down the UnrealScript language into easy to follow chapters that will quickly bring you up to speed with UnrealScript game programming.Unreal Development Kit Game Programming with UnrealScript takes you through the UnrealScript language for the Unreal Development Kit. It starts by walking through a project setup and setting up programs to write and browse code. It then takes you through using variables, functions, and custom classes to alter the game's behavior and create our own functionality. The use and creation of Kismet is also covered. Later, using replication to create and test multiplayer games is discussed. The book closes with code optimization and error handling as well as a few of the less common but useful features of UnrealScript.
