Number Formatting

Simple stock for formating numbers.
Returns number as string.
If only_num bool is set to false it will return formated number with commas ( 10,000 ) if true then with abbreviation ( 10k ).
If number is not round ( 2.3m, 10k, 159k ) it will be formated with commas ( 2,300,001 ).
At the moment it will only format till 999,999,999 after that it will output without commas or abbreviation in string.

Examples:
-------------------------------------------------
format_number(10000, true)
Result
10,000
-------------------------------------------------
format_number(10000, false)
or
format_number(10000)
Result
10k
-------------------------------------------------
format_number(2300000 , true)
Result
2,300,000
-------------------------------------------------
format_number(2300000 , false)
or
format_number(2300000 )
Result
2,3m
-------------------------------------------------
format_number(180390644 , false)
or
format_number(180390644 )
Result
180,390,644

Code:

stock format_number(num, bool:only_num = false)

{

        new s_num[16], million[16], thousand[16], hundred[16], szNum[32], p_length;

        num_to_str(num,s_num,15);

        p_length = strlen(s_num);

        

        switch(p_length)

        {

                case 1,2,3: formatex(szNum, charsmax(szNum), "%s", s_num);

                case 4,5,6:

                {

                        copy(thousand,p_length - 3, s_num[0]);

                        copy(hundred,3, s_num[p_length - 3]);

                        if (!only_num) { formatex(szNum, charsmax(szNum), "%s%s%s", thousand, num % 1000 == 0 ? "k" : ",", num % 1000 == 0 ? "" : hundred); }

                        else { formatex(szNum, charsmax(szNum), "%s,%s", thousand, hundred); }

                }

                case 7,8,9:

                {

                        copy(million,p_length - 6, s_num[0]);

                        copy(thousand,3, s_num[p_length - 6]);

                        copy(hundred,3, s_num[p_length - 3]);

                        if (!only_num) { formatex(szNum, charsmax(szNum), "%s%s%s%s%s", million, num % 1000000 == 0 ? "" : ",", num % 1000000 == 0 ? "" : thousand, num % 1000000 == 0 ? "" : ",", num % 1000000 == 0 ? "m" : hundred); }

                        else { formatex(szNum, charsmax(szNum), "%s,%s,%s", million, thousand, hundred); }

                }

                default : formatex(szNum, charsmax(szNum), "%s", s_num);

        }

        

        return szNum;

}

Re: Number Formatting

Bugsy wrote this function already and it was posted here. I'm quite sure that Bugsy's will be more efficient.

Also, you shouldn't be returning a string, strings should be pass by reference as it is done in function to which I linked.

Re: Number Formatting

i came across this post while trying to fix something that bothered me days ago
i googled ways to avoid zeros after float numbers and seems like `%g` is not embedded in pawn and a function i did returns something like this
https://i.ibb.co/Tb38hZz/image.png
i was going to use your thing but some zeros wont hurt after looking the mess you put together

Code:

#include <amxmodx>

enum PValueData{
    Number,
    Place_Value[2]
}

new PValue[][PValueData] = {
       { 1000000000, "B"},
          { 1000000, "M"},
             { 1000, "K"}
}

public plugin_init()
    register_srvcmd("f", "srvcmd_format")

public srvcmd_format(){
    new arg[16], num
    read_args(arg, charsmax(arg))
    num = str_to_num(arg)

    server_print(format_number(num))
}

public format_number(number){
    new abs_number = abs(number)
    for (new i = 0; i < sizeof(PValue); i++){
        if (abs_number >= PValue[i][Number]){
            return fmt("%s%.2f %s", number < 0 ? "-" : "", float(abs_number) / float(PValue[i][Number]), PValue[i][Place_Value])
        }
    }

    return fmt("%s%d", number < 0 ? "-" : "", abs_number)
}

Re: Number Formatting

I also have one but mine only supports integers and only adds commas:

PHP Code:


		
			
ftNumberAddCommasI(iNumber, szNumber[14] = "", const iSize = charsmax(szNumber))
{
    num_to_str(iNumber, szNumber, iSize);
    
    if (-1000 < iNumber < 1000)
        return szNumber;
    
    for (iNumber = strlen(szNumber) - 3; iNumber > ((szNumber[0] != '-') ? 0 : 1); iNumber -= 3)
        format(szNumber[iNumber], charsmax(szNumber) - iNumber + 1, ",%s", szNumber[iNumber]);
    
    return szNumber;
}

Re: Number Formatting

I'm using something in python that might be useful here:

PHP Code:


		
			
def convert_size(size_bytes):
   if size_bytes == 0:
       return "0B"
   size_name = ("B", "KB", "MB", "GB", "TB", "PB", "EB", "ZB", "YB")
   i = int(math.floor(math.log(size_bytes, 1024)))
   p = math.pow(1024, i)
   s = round(size_bytes / p, 2)
   return "%s%s" % (s, size_name[i])
