Has the compiler always rejected decimal numbers, ie:

3.4 * i
1.5 * i
i / 6.5

This is really frustrating and completely undesired functionality, :/

It's always done that. Hamsterspeak can only process integers.

I think it's probably because Hamsterspeak assumes anything with a period is a string/variable/constant/whatever and not a number, because QBASIC will allow you to pass a = a * 1.5.

Periods are not reserved for anything. You can name variables, scripts, etc. with periods in their names.

So when HSpeak sees a period in the middle of a number, its like seeing '1A2', which it can't understand.

But of course there are no fixed or floating point numbers.

I wonder if you could make a variable named 1.5.

Anyway, yeah. I always multiply my numbers. For example, the hero's x/y velocity in SG3 is stored at ten times its value in pixels.

It's odd that it's never come up in my scripts before my most recent project. On that note, it'd be funny to have your script read something like:

1.5 := 1

I think Hamsterspeak uses a different language from the rest of the OHR, TM.

I mean Hamsterspeak != coded in QBASIC.

HSpeak version 2 uses Euphoria, which of course has floating point numbers. What its coded in doesn't actually make any difference, it's James' coding that doesn't read them.

In fact, HSpeak version 1 was coded in QuickBasic, and did virtually the same job of compiling.

Just wanted to emphasize Moogle1's point (at least I think it was his point) that you can usually get away without decimals. Storing variables with factors of ten multiplied in is a good way. Using fractions is another. For instance, your variable*1.5 example would work just as well as variable*3/2. It'll cut off the decimal place, but it'll give you essentially what you want.

You mean, 3/2 works and 1.5 doesn't.

I would just like to point out that

var * 3 / 2

is not the same as

3 / 2 * var
or
(3 / 2) * var

3 / 2 works out to 1. I suggest you use paranthesis to save worrying:

Order of ops makes x*3/2 == (x*3)/2.

Yes, but the paranthesis insures that you don't get it in the wrong order.

"I would just like to point out that var * 3 / 2

Yes it is.

var = 6

6 * 3 / 2 = 9
3 / 2 * 6 = 9
3 * 6 / 2 = 9

var * 3 / 2 == 3 * var / 2 == 3 / 2 * var

Order of ops doesn't matter when you're only dealing with multiplication and division.
