TFS 1.X+ Gained experience in percent?

[Dran Ryszard]

Hi, can someone help me how to show gained experience in percent? I mean change whole numbers like 6400000000 to how much percent player get?
100% = 1
99% = 0.99
1% = 0.01
0% = 0

Its possible?

TFS 1.5 8.6 with modals

find the experience for that level.

So level 50 is 1,847,300 experience.
Level 51 requires 1,965,000 experience.

1,965,000 - 1,847,300 = 117,700.

Now you find the current amount of experience the player has.

Let's say 1,850,000.

current experience - level 50 experience = 2,700
1,850,000 - 1,847,300 = 2,700

So now we just find out how much of a percentage 2,700 is of 117,700.

(2700 / 117700) * 100 = 2.293%~

@Xikini Okey i know how to calculate percents xD, but how to calculate how much percent add monster?
I Think maybe use part of code what show it in game, but how to check what % of level player have before killing and after?
I thinked save % in storage, but i feel is stupid idea

I forgott say in first post - i wants change a value what is showed after monster kill, (that white numbers upper of character)

@Xikini i do something wrong couse not work When i calc it in calculator then i get correct results, but in game it show 0.0000%

void Player::addExperience(Creature* source, uint64_t exp, bool sendText/* = false*/)
{
    uint64_t currLevelExp = Player::getExpForLevel(level);
    uint64_t nextLevelExp = Player::getExpForLevel(level + 1);
    uint64_t rawExp = exp;
    if (currLevelExp >= nextLevelExp) {
        //player has reached max level
        levelPercent = 0;
        sendStats();
        return;
    }

    g_events->eventPlayerOnGainExperience(this, source, exp, rawExp);
    if (exp == 0) {
        return;
    }

    experience += exp;

    if (sendText) {
        std::string expString = std::to_string(exp) + (exp != 1 ? " experience points." : " experience point.");

        TextMessage message(MESSAGE_STATUS_DEFAULT, "You gained " + expString);
        sendTextMessage(message);
        
        float proc_exp = (exp/nextLevelExp)*100;
        
        g_game.addAnimatedText(std::to_string(proc_exp) + "%", position, TEXTCOLOR_DARKPURPLE);

        SpectatorVec spectators;
        g_game.map.getSpectators(spectators, position, false, true);
        spectators.erase(this);
        if (!spectators.empty()) {
            message.type = MESSAGE_STATUS_DEFAULT;
            message.text = getName() + " gained " + expString;
            for (Creature* spectator : spectators) {
                spectator->getPlayer()->sendTextMessage(message);
            }
        }
    }

            }
        }
    }

float proc_exp = (exp/nextLevelExp)*100;

exp and nextLevelExp are probably both integers.
In C++ when you divide a smaller integer against a larger integer the division will yield 0, because C++ truncates the fractional part in integer division.

Basically, the solution is to not do an integer division.
Explicitly cast them into a float.

float proc_exp = (static_cast<float>(exp) / static_cast<float>(nextLevelExp)) * 100;

@Xikini thanks, now work.
But...
I don't know where is problem, couse when monster add me 7% of level, then it show 3.57% (if i use variable currLevelExp, couse i think its correct, not a nextLevelExp ;D)

So i do this
But i think its not good but it work like i want xD

float proc_exp = ((static_cast<float>(exp) / static_cast<float>(currLevelExp)) * 100)*2;

Btw its possible to show only 2 numbers after comma?

float proc_exp = (static_cast<float>(exp) / static_cast<float>(nextLevelExp)) * 100;

// Format to two decimal places
std::stringstream stream;
stream << std::fixed << std::setprecision(2) << proc_exp;

g_game.addAnimatedText(stream.str() + "%", position, TEXTCOLOR_DARKPURPLE);

I don't know where is problem, couse when monster add me 7% of level, then it show 3.57% (if i use variable currLevelExp, couse i think its correct, not a nextLevelExp ;D)

I explained this up above, and you told me you know how to calculate percents already.
So good luck.

@Xikini i think i calculate it good? Couse variable "currLevelExp" = how experience we need to level up, so when i use variable "exp" (exp = how we experience get after kill monsters with all rates/boots) so when i (exp/currLevelExp)*100 = how i percent get?
So if monster add me 100xp when i need 6200 then its ~1.6%

But i think that variables its not what i mean, couse when player get few level for one monster, then its give crazy numbers of percents ;D

But thanks @Xikini and sorry for waste ur time.
