Hi, so I'm trying to figure out how I can format money in my mod. Basically I have a money mod that's printing the money to the hud but I'd like it so that instead of just having loads of numbers ($20543589"), I'd like it to look something like "$20,543,589".

I would expect you would have to do something like convert it to a string and then use some method to say for every 3 bits of data apply a comma but I'm a bit iffy on how I could do that.

Here's the code for the hud:

PHP Code:

SetHudTextParams(0.015, -1.0, HoldTime, HudColor);
ShowHudText(Client, -1, "[%s]\nMoney: $%i\nPayCheck: $%i\nKills: %i\nLevel: %i", ClientName, g_iMoney[Client], iPayCheck, g_iTotalKills[Client], g_iLevel[Client]); 


This is what the game displays:

Can we see what the game displays?

Ok done, sorry that's it's so big, I have no idea why it's not scaling down.

@hazukiy you could wrap it in [spoiler]<put image here>[/spoiler] tags.

For your question you'd probably need to:
1) IntToString your money integer
2) Create another string that has sizeof(string1)+RoundFloat(sizeof(string1)/3)
3) Have a for loop that counts backwards that reads data from string1 and puts it into string2 while also inserting commas every 3 loops.

This looks right to me right now but I could be overlooking something.

Right so I've got this far but I'm a little confused what you mean on the third part.

PHP Code:

for(new i = 3; i > 0; i--)
{
IntToString(g_iMoney[Client], sBuffer, sizeof(sBuffer)+RoundFloat(sizeof(sBuffer)/3));
}

Try this, I wrote this quickly without testing it but you get the logic if you read it.

PHP Code:

char money_buffer[32], raw_money_buffer[16];
IntToString(money_value, raw_money_buffer, sizeof(raw_money_buffer));

int skip;
for (int i = 0; i < sizeof(money_buffer); i++)
{
    // if no rest and i > 0 than insert comma
    if ( (i % 3) == 0 && i > 0)
    {
        money_buffer[i+skip] = ',';
        skip++;
        continue;
    }
    money_buffer[i+skip] = raw_money_buffer[i];
    
    if ( raw_money_buffer[i+1] == '\0' )
        break;
}

PrintToServer(money_buffer);

@Black-rabbit I'm pretty sure it should be for (int i=sizeof(money_buffer); i>=0; i--)
The reasoning behind this is that the string could be 23456, in which case I'm pretty sure the counting-up for loop would format it as 234,56.

...why would you be using sizeof instead of strlen?

[Mathias.]

@Powerlord sizeof is a predefine number that won't change, strlen will loop thru your char array until it reach a null terminator and return the actual size, since you already looping the string you can check for the null terminator yourself and break the loop.

@Wliu your right, I just wrote a quick concept, feel free to apply the change

Well, no, because as Wilu said you have to traverse it backwards to get commas in the correct position. Which means you need to know where the \0 is in advance.
