RGSS doesn't allow decimals?

[Ellie]

I'm making a minimap, and so that I can have any sized map I'm using this to work out a number to multiply things by:

wide = 119 / $game_map.width
    high = 82 / $game_map.height

The idea is, on a 100x100 sized map this should return:

wide = 1.19
high = 0.82

Then this will be multiplied by the player's x and y positions to make the co'ords to use for the player sprite on the minimap.

The problem is, RGSS always rounds these to a whole number for some reason.

p "#{wide}, #{high}"

Returns

"1, 0"

Is there any way I can do this?

Thanks in advance.

you can make it do decimals like this
wide = 119.0 / $game_map.width
adding the .0 at the end indicates it is a floating point operation.
Also, if you're only working with variable, you can convert to float like so
$game_map.width.to_f
Hope it helps

Thanks, it works .

No worries. From what I know, most programming/scripting languages only use integers if you don't specify otherwise, mostly because the use of floating points is pretty rare in programming, it's not needed much.

That's not exactly true; most interpreted programming languages will use integer by default unless specified otherwise. And floating point arithmetic is pretty widely used, much more so than simple integers; the science community would collapse on itself without it, leaving a large, black hole of hate and disbelief.

I assume this has been solved, however.
