Can I format without rounding?

Yes, you can format a floating-point number to show two decimal places without rounding by converting it to a string and then slicing it. Here’s how you can do it:

Using String Manipulation

num = 458.541315
formatted_num = str(num)  # Convert to string
if '.' in formatted_num:
    formatted_num = formatted_num[:formatted_num.index('.') + 3]  # Keep two decimal places
print(formatted_num)  # Output: 458.54

Using Decimal for Exact Control

You can also use the Decimal class from the decimal module, which allows for more precise control over the formatting:

from decimal import Decimal

num = Decimal('458.541315')
formatted_num = num.quantize(Decimal('0.00'), rounding='ROUND_DOWN')
print(formatted_num)  # Output: 458.54

In this example, ROUND_DOWN ensures that the number is truncated rather than rounded.
