[JASS] Problem with Reals; Problem with Round

[emperor_d3st]

Hi, I want to stuff reals into multiboards but I don't want to see something like this in my multiboard: "52.76812...."
I want the real to have only one decimal after the "." So it should look like this: 52.7*
I haven't found a function or syntax which does this so I had to solve this with a custom function that multiplies it by ten converts it to integer and does funny things with it.
My first question is: is my custom function necessary or is there a way to do this with default functions/syntaxes?

The other thing is. I haven't found a round function either. I had to make one for that too.
So that's my second question.

Hm, well, maybe convert the real value to a integer value? would not show a single decimal after the ".", but oh well.

Converting from real to integer results in truncating. So if you convert a real: 1.78 to an integer it becomes 1.

R2S() (Real to String) seems to universally displays numbers with 3 decimal points.

So you'll need something like:

local string s = I2S(R2I(x*10)) // where x is a real-type value you want to display
set s = SubString(s, 0, StringLength(s) - 1) + "." + SubString(s, StringLength(s) - 1, StringLength(s))

Oh, I didn't know that it's universal.
Thank you, it's shorter than mine.
I'll take this as a "There's no way to do that" for my questions.

SubStrings. Find the ., and then truncate everything after the first character after the '.' .

R2SW(r, 0, 1) does exactly what you wish.
