Hi.
I creating my own stats plugin and i have problem with displayed float value.

For example, for kill - you got 1.0 point and for suicide/death - you got -0.5 point.
Example player has 3 kills and 1 death and i want to display 2.50 (3 * 1.0 - 1 * 0.5), but plugin display 2.49
Example code:

new Float:points[33];

public event_death()
{
new attacker = read_data(1);
new victim = read_data(2);

points[attacker] += 1.0;
points[victim] -= 0.5;
}

public show_points(id)
{
client_print(id, print_chat, "%.2f", points[id])  //Show 2.49, not 2.50
}

Where i got error ?
Thanks for any help.

It's a common problem with floats. Precision is off sometimes, so you may see a value being off by 0.000001 or whatever.
You can round to 2 decimal places if you don't need more than that:

stock Float:round(Float:value, decimals)
{
    new Float:p = float(power(10, decimals));
    return float(floatround(value * p, floatround_floor)) / p;
}

This might also have issues with precision even though we are limiting to specific decimal places.

Still i got problem with this.
I use your stock everywhere where i got a float and it dit not help.

And i have question, how i use your stock ?
Possibly i make fault when using this:

points[id] = round(0.5, 1);
points[id] += round(1.5, 1);

It's work ?

You should only use it when you display the value. Also, the second argument should be 2 if you want to round to 2 decimal places.

fysiks, still dont work.

I save my data to sql:
sql - 3.50 (good)
plugin, when i display value - 3.49 (bad)

Stock from exolent dont working.
Where is error now ?

There is no error in your code.
The problem is with floating point precision.

Ok, thanks for any help.

think to use nVault if you want to save data

... That has nothing to do with the discussion.
