I do believe it is just a helpful hint letting you know, the programmer, as to what is
really happening in the background.
The currency is not a floating point storage media. It is just a int64 type.
You can in theory use the DIV and the results should be the same, but it'll actually
operate faster in code. I used an old version of FPC and I had to cast to a Int64 to use
the DIV, but the results were the same except using binary math instead.
Using / allows you to specify fractions in the division and more code in the
background.
The hint is there to let you know you can use DIV for non fraction divides for performance
of code if you wish too. Maybe the Hint should be worded differently. ?
