why does floatformat:2 adds a comma after the hundred place

I have a Django project and I have a {{account.current_balance}} tag in my HTML. I also included the type of data it is just in case it matters. I understand #1 and #2, but I don't understand why with #3, adding intcomma would add a comma after the hundred place.

1. Tag without floatformat or intcomma

   {{ account.current_balance }}

output:
Current Balance - Type
303.6000000000000 - Decimal

2. Tag with floatformat:2

   {{ account.current_balance|floatformat:2 }}

output:
Current Balance - Type
303.60 - Decimal

3. Tag with floatformat:2 with intcomma

   {{ account.current_balance|floatformat:2|intcomma }}

output:
Current Balance - Type
,303.60 - Decimal
adding models.py and views.py

class BankAccount(models.Model):
    beginning_balance = models.DecimalField(max_digits=10, decimal_places=2)

class Transaction(models.Model):
    amount = models.DecimalField(max_digits=10, decimal_places=2)
    transaction_date = models.DateField()

class UserHome(LoginRequiredMixin, AccountContextMixin, ListView):
    model = Transaction
    template_name = 'base_app/home.html'
    context_object_name = 'transactions'
    paginate_by = 20

    def get_queryset(self):
        user = self.request.user
        return self.model.objects.filter(user=user).filter(status="Posted").order_by('-transaction_date')

    def get_context_data(self, **kwargs):
        context = super().get_context_data(**kwargs)
        
        total_balance = 0
        
        home_get_accounts = BankAccount.objects.filter(in_report='Yes')
        for account in home_get_accounts:
            posted_transactions_sum = Transaction.objects.filter(bank_account=account, status='Posted').aggregate(total=models.Sum('amount'))['total'] or 0
            current_balance = posted_transactions_sum + account.beginning_balance
            account.current_balance = current_balance  # Adding current_balance attribute to account instance

            total_balance += current_balance
            
            print(type(total_balance))
    
        context['home_get_accounts'] = home_get_accounts #for Beginning Balances
        context['total_balance'] = total_balance
        context['total_balance_type'] = type(total_balance).__name__
        return context

This is a bug in Django having issue #35172. It has been solved for the LTS releases in versions 3.2.25+ and 4.2.11+, for the current major version it has been solved in version 5.0.3 onwards.

The solution to fix this would be to upgrade to a version of Django where this is fixed.
