< What is this equation useful? For a lot of things, here's an example how to move a progress bar when you know the percent loaded:
< <code haxe>progressBar.width = lEquation (Int, 0, 530, percent, 0, 100);</code>
< T is the type you want to return, Int or Float
< 0 - 530 means that the width of the progressBar will change from 0 to 530 when the percent will take values from 0 to 100

> What is this equation useful? For a lot of things that changes their values linearly. Here's an example how to move a progress bar when you know the percent loaded:
> <code haxe>progressBar.width = lEquation (0, 530, percent, 0, 100);</code>
> 0 - 530 means that the width of the progressBar will change from 0 to 530 when the percent will take values from 0 to 100.
> I find it useful because you don't have to think the formula again and again, you know visually what values to put in the function.
