Rounder

Rounder is a fast, lightweight implementation of the built-in round function in Python. It allows for advanced rounding with the use of artificial intelligence to round fully and completely. It rounds even better than the built-in round function with it's rounding accuracy. It's made to be as customizable as possible with options such as how many digits you want rounded (even though that's a granted feature), change return format on error, and the option to disable warnings.

How it works and how to use

Python 3.8 and above supported! You can use it just like the built-in round function, with option for round to digit place (for example: the hundredths place) and it will round the float you passed to the digit place you specified. If you didn't specify a round place it will automatically round by the whole number. The return value for whole numbers will always be int, while floats will obviously be a float.

Example uses

>>> import rounder
>>> rounder.round(3.14159)
Output: 3
Type: int
>>> rounder.round(3.14159, 1)
Output: 3.1
Type: float

Installation

Installation is as simple as moving the rounder folder to your working directory. There is no PIP installation at this time.

Is this production ready?

Probably not. There are many use cases that just haven't been tested yet. I do use Rounder a lot for some of my personal projects because it has been stable for my use cases.

Why use Rounder

Comparing to built-in round function

Rounder, compared to the built-in round function of Python, is more 'advanced' and fast. What I mean is that it rounds beyonds the digit place you want for a more exact round with the help of artificial intelligence. For example: 3.44445 rounded to the tenth place should be 3.5 if you round all the way through, which Rounder identifies correctly. Although it should be 3.5 (if you round all the way), the built-in round function defines it as 3.4. You may have different views on how to round, such as not rounding all the way through, so of course you can always use the built-in round function.

Speed

Rounder, overall, is faster than the built-in round function. You can check this info yourself by taking a look at the latest build tests.

Why Rounder was made

I just wanted a fun challenge, and recreating a more advanced version of the built-in round function without using any modules sounded like a hard and perfect challenge for me :)
