## Overview
The **`Double.exponent` property** of a value of type double in Swift is the exponent of a floating-point value. When we speak of exponents, we are referring to the integer part of the logarithm of the value's magnitude.

## Syntax
```swift
Double.exponent
```
## Return value
The value returned is the exponent of the double value. This returned value is an integer.
## Code example


// create some double values
let d1 = 12.44
let d2 = 1.23333
let d3 = 100.1
let d4 = 1.0

// print the exponents
print(d1.exponent)
print(d2.exponent)
print(d3.exponent)
print(d4.exponent)

## Code explanation
In the code above,
* In lines 2-5, we create the double values or the floating-point numbers.
* In lines 8-11, we print the exponents of the double values.

What is the Double.exponent property in Swift?

Double.exponent in Swift returns the exponent part of a floating-point value, expressed as an integer.
