Difference between Floor Division and Float Division in Python
An expression's data type typically depends on type of its parameters. The majority of operators follow this requirement; for example, when adding two numbers, the outcome must also be an integer. Due to the two conflicting assumptions, this doesn't work out well in the situation of division. Sometimes we want the result of division to be a precise floating-point number, while other times we want an integer result that has been rounded down.
The Python definition for division (/) generally just considered the arguments. For instance, 20/7 was divided by 2 in Python 2.7 because both parameters were integers. However, because the arguments are floating point numbers, 20/7 will produce 2.85 as the output.
The division operators in Python are // and /. Which one you choose depends on the outcome you seek. A floating-point value is returned by the single forward slash (/) operator, which is referred to as float division.
Integer division and float division are the two types of division available in Python. The floor of a division is returned by integer division. Since integer values are exactly recorded, using them in comparisons is secure.
The double forward slash // operator, on the other hand, returns a floored value, specifically a floored floating point or integer value.
The ability to divide two integers and have the quotient returned is provided by the division operator, which divides the leftmost number by the rightmost number.
Division operators come in two different varieties:
Floor Division in Python
The floored number of the quotient is returned when doing floor division in Python using the // operator. Integer division, which would round all the number, operates differently than this. This operates instead by giving the floor value.
Let's look at few samples to see how this actually functions:
What occurs with negative numbers is one intriguing observation concerning this:
-7.0 // 3
This makes logical sense. The result will be floored, which means that while we might anticipate it to be equivalent to -2.0, rounded down, the actual value is -3.0.
The // operator in Python can be used to do floor division, also referred to as integer division. This operation would divide the first parameter by the second argument, converting the result to math by rounding it to the closest whole number.
In some cases, the / operator will output both floats and integers, giving conflicting results. Therefore, utilising the / operator may require additional steps to assure a consistent output if your programme depends on integers.
There really are a few additional methods for changing the quotient between two numbers so that it functions properly with your software. Using various methods can give you greater control over the outcomes since, for instance, you will not always would like to go round the value down.
Divide a Floor by a Negative Number
When the operand is negative, the largest integer that is less than or equal to the outcome of ordinary division will be returned by floor division. To demonstrate how this operates, let's use same operands as before:
3.75 3 -4
Python Float Division
Use the / operator in Python to divide float values. The float division is returned by the division operator (), which accepts two parameters. A floating-point estimate of the division's outcome is produced by float division.
The term "float division" refers to a division process that continues up to a float number's capacity. In other words, the result includes a decimal portion. The Python / operator can be used to divide floats. Regardless of whether two values are integers or floats, this operator always returns a float as the quotient.
The / division operator divides floats and takes two inputs. A straightforward illustration is result = a/b.
The / operator will be used in the sample programme that follows to divide two variables into floats.
When an integer is required or you need to provide the smallest integer that is less than and equal to the input, you typically use the floors division operator (//).
The output will be an integer if the components are both integers. The result will be a float if the other operand is a float.
The // operator creates lines that are simple to read.
