> I propose a new function for ArithmeticUtils that takes a number and it
> returns the integer closest to it. Some use cases are:
> # {*}Rounding Numbers{*}: The most common use case is to perform rounding on
> numbers, where you would want to find the closest integer value to a given
> number. This is often required when dealing with mathematical or scientific
> computations where you want to reduce the precision for simplicity or due to
> some limitation.
> # {*}Graphics Programming{*}: In computer graphics, you often deal with
> pixel values that must be integers. If you're doing any kind of
> transformation or computation that results in non-integer values, you might
> use a function like this to find the closest integer that can represent a
> pixel value.
> # {*}Discretization{*}: In some fields, it's necessary to transform
> continuous data into discrete counterparts for specific algorithms. For
> instance, in machine learning or statistical analysis, some algorithms
> perform better or can only work with discrete values.
> # {*}Data Type Limitations{*}: Sometimes, you're working with a system or
> library that only accepts integers. In such cases, a function like this would
> be necessary to convert your numbers into a format that the system can
> understand.
> # {*}Resource Allocation{*}: In resource allocation scenarios, such as
> assigning tasks to workers, distributing goods, or scheduling, you often need
> to work with whole units. So, you might need to round up or down to the
> nearest integer.
