Questions about calculate the square root using Accelerate

I am currently studying the Accelerate library by referring to Apple documentation.

Here is the link to the referenced document: https://developer.apple.com/documentation/accelerate/veclib/vforce

When I executed the sample code provided at the bottom of the document, I found a case where the results were different.

let n = 10_000
 
let x = (0..<n).map { _ in
    Float.random(in: 1 ... 10_000)
}
 
let y = x.map {
    return sqrt($0)
}

and

let y = [Float](unsafeUninitializedCapacity: n) { buffer, initializedCount in
    vForce.sqrt(x,
                result: &buffer)
    
    initializedCount = n
}

The code below is provided to observe the issue described above.

import Accelerate
 
Task {
    let n = 1//10_000
 
    let x = (0..<n).map { _ in
        Float(6737.015)//Float.random(in: 1 ... 10_000)
    }
 
    let y = x.map {
        return sqrt($0)
    }
 
    try? await Task.sleep(nanoseconds: 1_000_000_000)
 
    let z = [Float](unsafeUninitializedCapacity: n) { buffer, initializedCount in
        vForce.sqrt(x, result: &buffer)
 
        initializedCount = n
    }
}
 

For a value of 6737.015 when calculating the square root:

Using the sqrt(_:) function gives the result 82.07932,

While using the vForce.sqrt(_:result:) function gives the result 82.07933.

Using a calculator, the value comes out as 82.07932139, which shows that the result from vForce is incorrect.

Could you explain the reason behind this difference?
