(* |
23 |
* This unit provides a custom data type, hwFloat. |
|
24 |
* |
|
25 |
* hwFloat represents a floating point number - the value and operations |
|
26 |
* of this numbers are independent from the hardware architecture |
|
27 |
* the game runs on. |
|
28 |
* |
|
29 |
* This is important for calculations that affect the course of the game |
|
30 |
* and would lead to different results if based on a hardware dependent |
|
31 |
* data type. |
|
32 |
* |
|
33 |
* Note: Not all comparisons are implemented. |
|
34 |
* |
|
35 |
* Note: Below you'll find a list of hwFloat constants: |
|
36 |
* E.g. _1 is an hwFloat with value 1.0, and -_0_9 is -0.9 |
|
5124 | 37 |
* Use and extend the list if needed, rather than using int2hwFloat() |
38 |
* with integer constants. |
