# How To Divide In Python?

Python has a unique selection of functions that allow users to carry out complex calculations.

Because of this, there are a range of uses in terms of data processing and analysis.

In order to generate usable statistics, it is necessary to appreciate the different methods of division within python.

These are integer and float division. Here is a guide into how you can make use of each method, and how to carry out certain calculations when you need it.

## Integer Division

Firstly, integer division is the preferred method of division within many python programs that need to be done fast.

This is because there is less processing time, due to the single unit that the data is put into.

The program does not need to work as hard, which means that you can process more data within a short amount of time.

Integers are easy to notice within python, because they do not use decimals.

They rely on rounding to the nearest whole number, which is what makes them easier for the program to process.

However, in some cases, the decimal point and everything that comes afterwards is ignored entirely.

The main drawback of the integer division method is that it is less accurate than other methods.

This can therefore limit how it should be used.

For example, it is harder to draw scientific conclusions based on figures that have been calculated using the integer division method.

If you have a lot of data that needs to be processed in the right form, then integer division could be an ideal calculation method for generating rough estimates.

It could also be used if the need for accuracy is less pressing.

To carry out this method, you should use the symbol // as a division operator. Rounded numbers are also needed on either side of the calculation in order to generate appropriate integer figures.

For example, outcome = a // b. The answer is typically rounded down, and presented as a whole number without decimals.

## Float Division

For a more accurate calculation, float division is preferred. This does not involve rounding, and decimals are included in the sums.

The name comes from the idea that these numbers are ‘floating-points’ due to their decimals.

These calculations are far more precise than integer divisions, which is why they are ideal for a wider range of situations.

As a general rule, python will recognize your output as digital when there is a decimal point.

The symbol for float division can be seen as a single line. An example of this is outcome = a.25 / b.

## Changing A Float To Integer

If you need to cross-reference your calculations, or change the format of your data, then you may want to change float figures into integers.

This can easily be done on python, as can integers be changes to float. Floats will lose any numbers after the decimal point, and the point itself will go.

This can be useful when it comes to presenting large bodies of data, information, and creating visual aids such as charts.

If you want to change a float to an integer, all you have to do is carry out the int() function.

For those that are looking to change their integers into floats, the float() function will add a .0 to the end of the figure.

This can give a more scientific feel without impacting the results. Additionally, this conversion could be used if you are changing a particular test that you are running.

It’s important to be adjustable, which is why changing the way that data is processed by python is easy to carry out.

## How To Check

When you are processing a high amount of data, it can be easy to lose track of certain things.

Because of this, it can be useful to remember the methods of checking whether a particular number is an integer or a float.

This is especially useful if you are still trying to learn about the different types of figures within python.

To check if a number is an integer, use the format check_integer = isinstance (a, int). Where there is the letter ‘a’, will be where the number in question should go.

Once this is run, python will show you if the statement is true or false. If it is true, then it means that the number is in fact an integer.

If the statement says that it is false, then it is not an integer, and it is therefore a float.

To check whether a number is a float, there is a similar test that you can carry out. This is check_float = isinstance (a, float).

A similar outcome will follow this formula as the integer check, and it is worth knowing what format your data is being processed in.

It is important to understand what kind of data python thinks you are using, because it can influence how it is being processed.

In turn, that can have an impact on the type of generalizations and conclusions you are drawing as a result of certain calculations.

Make sure you are paying attention to your chosen method of data processing, and that you are being as consistent as possible with the formation of tables and calculating figures.

Additionally, it is important that you are making the most appropriate choice based on the use of data.

For example, scientific research should use float numbers and division methods, whereas more general assumptions can be made as a result of integer calculations.

## Summary

Python has an enormous amount of uses when it comes to processing large amounts of data within a short time frame.

It is easy to carry out calculations and start to present findings in the form of graphs and charts when needed.

Float division methods are the more accurate, whereas integer divisions typically provide a ballpark figure that is best for assumptions and rough estimates.
