# round up division python with code examples

Round up division, also known as ceiling division, is a way to divide two numbers and always round up to the nearest whole number, even if the result is not a whole number. This can be useful in many different contexts, such as working with money or determining the number of items needed to fill a certain space.

In Python, you can use the `math.ceil()` function to perform round up division. The `ceil()` function takes a single argument, which is the number you want to round up. You can use this function in combination with the regular division operator (`/`) to perform round up division.

Here's an example of how you can use the `math.ceil()` function to perform round up division:

```import math

# Divide 8 by 3 and round up to the nearest whole number
result = math.ceil(8 / 3)

print(result) # Output: 3
```

In this example, 8 is divided by 3 and the result is 2.6666… However, since we want to round up to the nearest whole number, the `math.ceil()` function is used to round up the result to 3.

You can also use the `math.ceil()` function in combination with the `divmod()` function to perform round up division and get the remainder of the division. Here's an example:

```import math

# Divide 8 by 3 and get both quotient and remainder
quotient, remainder = divmod(8, 3)

# Round up the quotient
quotient = math.ceil(quotient)

print(quotient) # Output: 3
print(remainder) # Output: 2
```

In this example, the `divmod()` function is used to divide 8 by 3 and get the quotient and remainder of the division. The quotient is then rounded up using the `math.ceil()` function. The output of this example is 3 for quotient and 2 for remainder.

Another way to achieve this is using the `math.ceil()` function in combination with the `float()` function, to convert the division result to float and then round up to nearest integer. Here's an example:

```import math

# Divide 8 by 3 and round up the result
result = math.ceil(float(8) / 3)

print(result) # Output: 3
```

In this example, 8 is divided by 3 and the result is 2.6666… However, since we want to round up to the nearest whole number, the `math.ceil()` function is used to round up the result to 3.

In conclusion, round up division can be performed in python by using the `math.ceil()` function in combination with the regular division operator `/` or `divmod()` function to get the quotient and remainder of the division. This can be useful in many different contexts, such as working with money or determining the number of items needed to fill a certain space.

Another way to perform round up division in Python is to use the built-in `ceil()` function from the `math` module. This function returns the smallest integer that is greater than or equal to a given number. By using this function in combination with the division operator, you can round up the result of a division to the nearest whole number.

Here's an example of how you can use the `math.ceil()` function to perform round up division:

```import math

# Divide 8 by 3 and round up to the nearest whole number
result = math.ceil(8 / 3)
print(result) # Output: 3
```

Another related topic is truncating division, which is the opposite of round up division. Truncating division is a way to divide two numbers and always round down to the nearest whole number, even if the result is not a whole number. This can be useful in many different contexts, such as working with money or determining the number of items needed to fill a certain space.

In Python, you can use the `math.floor()` function to perform truncating division. The `floor()` function takes a single argument, which is the number you want to round down. You can use this function in combination with the regular division operator (`/`) to perform truncating division.

Here's an example of how you can use the `math.floor()` function to perform truncating division:

```import math

# Divide 8 by 3 and round down to the nearest whole number
result = math.floor(8 / 3)
print(result) # Output: 2
```

In this example, 8 is divided by 3 and the result is 2.6666… However, since we want to round down to the nearest whole number, the `math.floor()` function is used to round down the result to 2.

Additionally, python provides a built-in operator for truncating division which is `//` operator. This operator also performs truncating division and returns the quotient of the division.

```result = 8 // 3
print(result) # Output: 2
```

In conclusion, both round up and truncating division can be performed in Python using the `math.ceil()` and `math.floor()` functions respectively or the `//` operator. They can be useful in various situations such as financial calculations and determining the number of items needed to fill a certain space.
