To create a decimal number variable that can be added to another number, you would need to use a float variable.
A float variable is a type of data variable that can store decimal numbers. It can hold both whole numbers and fractions, making it suitable for numerical operations that involve decimal values.
In most programming languages, you can declare a float variable by using the float keyword, followed by the variable name. For example, in Python, you would write:
```python
my_float_variable = 3.14159
```
This would create a float variable named `my_float_variable` and initialize it with the value of pi.
Once you have a float variable, you can perform mathematical operations with it, such as addition, subtraction, multiplication, and division. For example:
```python
my_float_variable = 3.5
another_number = 2.1
result = my_float_variable + another_number
```
In this example, the variable `result` would store the value of `5.6`, which is the sum of `3.5` and `2.1`.
Therefore, to perform addition with a decimal number, you would need to create a float variable.
