## Overview
**`Double.infinity`** in **Swift** returns a positive infinity value. When compared, it is greater than all finite values and equal to infinite values.
## Syntax
```swift
Double.infinity
```
## Return value
This method returns an infinity value **`inf`**.
## Code example

// Get infinity
let infValue = Double.infinity

// Print the infinity value
print(infValue)

// Compare with other values
let comp1 = infValue > 1 ? "greater" : "lesser"
let comp2 = infValue < 1 ? "lesser" : "greater"
let comp3 = infValue == Double.infinity ? "equal" : "lesser"

// Print the results
print(comp1)
print(comp2)
print(comp3)

## Explanation
* **Line 2**: We declare the infinity value using `Double.infinity`, and store it in the variable **`infValue`**.
* **Lines 8 to 10**: We compare the infinity value `infValue` with some other values and infinity itself.
* **Lines 13 to 15**: We print the results of each comparison to the console.
