# Data Types

## Basic Data Types

* **\[string]** — a string used to represent text.
* **\[char]** — a 16-bit character in Unicode format, used to represent individual characters.
* **\[byte]** — an 8-bit numeric type, typically used for handling binary data.
* **\[int]** — a 32-bit integer, a common type for working with integer values.
* **\[long]** — a 64-bit integer, used for large integer values.
* **\[bool]** — a boolean type that accepts True or False values, used for logical operations.
* **\[decimal]** — a 128-bit floating-point number, optimal for financial calculations with high precision.
* **\[single]** — a 32-bit floating-point number.
* **\[double]** — a 64-bit floating-point number, well-suited for scientific and engineering calculations.
* **\[DateTime]** — a data type for storing date and time.
* **\[xml]** — an object for working with XML data.
* **\[array] \[string\[]]** — an array, can be created with examples: `@(1,2,3)` or simply `(1,2,3)`. It is important to remember that `(1)` is not an array, but a scalar value. Arrays allow storing sets of elements of the same or different data types. More information can be found in the official documentation on arrays:

* **\[hashtable]** — a hash table or dictionary with keys and values, for example: `@{1=11; 2=12; 3=14}`. It is convenient for associative data storage. More about hash tables can be read in the reference materials:

## Type Conversion

* Converting a string value to a date:

```
powershell"5/7/07" -as [DateTime]
```

* Alternative conversion using type casting:

```
powershell[datetime]"5/7/07"
```

* Using a method from the Convert class:

```
powershell[Convert]::ToDateTime("5/7/07")
```

* Example of converting a numeric expression to a string:

```
powershell(1 + 1 * 2).ToString()
```
