Function "RoundFloat" - Kwarde - 26.02.2011

Hi,
First of all: I know, there is a "floatround" function. But that function rounds a float to an integer.
Someone needed a function that rounded the number behind the dot (eg. 5.555 = 5.6)
So I tried to make it. It didn't work :/. I tried it on two ways, both failed.

First one

pawn Код:

stock RoundFloat(Float:value)
{
    new Float:output1,
        Float:output2,
        Float:output,
        tmpstr[50],
        split[2][25]
    ;
    strmid(tmpstr, value, 0, false);
   
    for(new i = 0; i < strlen(tmpstr); i++){
        if(tmpstr[i] == '.'){
            strmid(split[0][0], tmpstr[0], 0, i);
            strmid(split[1][i], tmpstr[i], 0, false);
            break;
        }
        else continue;
    }
   
    output1 = strval(float(split[0]));
    output2 = strval(float(split[1]));
    output = floatadd(Float:output1, Float:output2);
    return Float:output;
}

(this one is from line 5-27)

Can someone help me?
Especially with the second one (that one'll return as string, because I didn't found a function that could change a string to float or int to float).
I'm also really annoyed about line 12:

pawn Код:

format(str, 50, "%s", floatstr(input));

It says argument mismatch. I don't get it! the 'input' is a float, so it should change 'float' to a string!

p.s.
Yes, I'd also tried this:
1- String to Value (strval)
2- Value to Float (float)
Didn't work either.

Re: Function "RoundFloat" - bigcomfycouch - 26.02.2011

Floatstr turns a string into a float. You are using it wrong.

Re: Function "RoundFloat" - Kwarde - 26.02.2011

rofl now I see why.
I've got flue and I'm tired, I can't think clean. I was thinking like this: floatstr = float string = float INTO string.
Bit stupid name for a function...
Any way to change to string? Or wait I already have an idea.
