You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: float64s_bench_test.go
    path of file: ./repos/pie/pie
    
    the code of the file until where you have to start completion: package pie

import (
	"math/rand"
	"testing"
)

func BenchmarkFloatMedianSmall(b *testing.B) { benchmarkFloatMedian(b, 20) }

func BenchmarkFloatMedianMedium(b *testing.B) { benchmarkFloatMedian(b, 800) }
func BenchmarkFloatMedianLarge(b *testing.B)  { benchmarkFloatMedian(b, 1000000) }

func benchmarkFloatMedian(
    
func benchmarkFloatMedian(b *testing.B, size int) {
	// Make the random numbers below deterministic
	rand.Seed(123)

	a := make(Float64s, size)
	for i := range a {
		// As many possible values as slots in the slice.
		// Positives and negatives.
		// Variety, with some duplicates.
		a[i] = -0.5 + rand.Float64()
	}

	b.ResetTimer()
	for i := 0; i < b.N; i++ {
		// m := a.MedianOld()
		// m := a.medianCheck()
		m := a.Median()
		sinkFloats += m
	}
