sort.SearchFloat64s()

The SearchFloat64s() function is an inbuilt function of the sort package which is used to search for the given element (x) in a sorted slice of float64s and returns the index as specified by Search().

It accepts two parameters (a []float64, x float64) – a is the sorted slice of float64 type and x is a float64 type element to search and returns the index as specified by Search.

Note: The SearchFloat64s() result is the index to insert the elements (x), if x is not present (it could be len(a)). The slice must be sorted in ascending order.

Syntax:

func SearchFloat64s(a []float64, x float64) int

Parameter(s):

  • a : A sorted slice of float64s.
  • x : A float64 type elements to be searched within a.

Return Value:

The return type of the SearchFloat64s() function is an int, it returns the index as specified by Search.

Example 1:

// Golang program to demonstrate the
// example of sort.SearchFloat64s() Function

package main

import (
	"fmt"
	"sort"
)

func main() {
	a := []float64{10.50, 20.0, 25.60, 27.50, 30.0}

	x := 25.60
	fmt.Println(sort.SearchFloat64s(a, x))

	x = 30.0
	fmt.Println(sort.SearchFloat64s(a, x))

	x = 10.5
	fmt.Println(sort.SearchFloat64s(a, x))

	// items not found case
	x = 10.0
	fmt.Println(sort.SearchFloat64s(a, x))

	x = 35.50
	fmt.Println(sort.SearchFloat64s(a, x))
}

Output:

2
4
0
0
5

Example 2:

// Golang program to demonstrate the
// example of sort.SearchFloat64s() Function

package main

import (
	"fmt"
	"sort"
)

func main() {
	a := []float64{10.50, 20.0, 25.60, 27.50, 30.0}

	x := 25.60
	i := sort.SearchFloat64s(a, x)
	fmt.Printf("Element %g found at index %d in %v\n", x, i, a)

	x = 10.0
	i = sort.SearchFloat64s(a, x)
	fmt.Printf("Element %g not found, it can inserted at index %d in %v\n", x, i, a)

	x = 40.50
	i = sort.SearchFloat64s(a, x)
	fmt.Printf("Element %g not found, it can inserted at index %d in %v\n", x, i, a)
}

Output:

Element 25.6 found at index 2 in [10.5 20 25.6 27.5 30]
Element 10 not found, it can inserted at index 0 in [10.5 20 25.6 27.5 30]
Element 40.5 not found, it can inserted at index 5 in [10.5 20 25.6 27.5 30]

Example 3:

// Golang program to demonstrate the
// example of sort.SearchFloat64s() Function

package main

import (
	"fmt"
	"sort"
)

// Main function
func main() {
	a := []float64{10.50, 10.0, 5.15, 20.50, 25.12}

	b := []float64{50.50, 10.10, 40.40, 30.30, 20.20}

	var x1, x2 float64
	x1 = 20.50
	x2 = 30.30

	// Sorting  both slices of float64s
	sort.Float64s(a)
	sort.Float64s(b)

	// Printing both slices of float64s
	fmt.Println("a: ", a)
	fmt.Println("b: ", b)

	// Searching elements
	ind1 := sort.SearchFloat64s(a, x1)
	ind2 := sort.SearchFloat64s(b, x2)

	// Displaying the results
	fmt.Println("Result 1: ", ind1)
	fmt.Println("Result 2: ", ind2)
}

Output:

a:  [5.15 10 10.5 20.5 25.12]
b:  [10.1 20.2 30.3 40.4 50.5]
Result 1:  3
Result 2:  2
