"Integer Float" Exact Conversion to Float

I am working with a library that uses int for representing money amounts. For example, the following is what this looks like:

599 --> $5.99
500 --> $5.00
5 --> $0.05
0 --> $0.00
-599 --> $-5.99

I wrote the following function which does an exact float conversion without causing floating point errors, but what I am wondering is if I am approaching this the wrong way or if there is a much cleaner solution.

def money_int_to_float(value: int) -> float:
    neg: str = '-' if value < 0 else ''
    value = abs(value)

    cents: int = value % 100
    remaining: int = value - cents
    dollars: int = int(str(remaining).removesuffix('00'))
    return float(f'{neg}{dollars}.{str(cents).zfill(2)}')

My reasoning for wanting an exact float conversion is that when dealing with money you can never be too careful with floats.

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...
