Functions

func Avg

func Avg(values ...float64) float64

Returns the average value of the given values.

Example

package main

import (
	"fmt"

	"github.com/ayonli/goext/mathx"
)

func main() {
	fmt.Println(mathx.Avg(1))
	fmt.Println(mathx.Avg(1, 2))
	fmt.Println(mathx.Avg(1, 2, 3))
}

Output:
1
1.5
2

func Max

func Max(first float64, rest ...float64) float64

Returns the maximal value from the given values.

Example

package main

import (
	"fmt"

	"github.com/ayonli/goext/mathx"
)

func main() {
	fmt.Println(mathx.Max(1))
	fmt.Println(mathx.Max(1, 2))
	fmt.Println(mathx.Max(1, 2, 0.5))
}

Output:
1
2
2

func Min

func Min(first float64, rest ...float64) float64

Returns the minimal value from the given values.

Example

package main

import (
	"fmt"

	"github.com/ayonli/goext/mathx"
)

func main() {
	fmt.Println(mathx.Min(1))
	fmt.Println(mathx.Min(1, 2))
	fmt.Println(mathx.Min(1, 2, 0.5))
}

Output:
1
1
0.5

func Product

func Product(first float64, rest ...float64) float64

Returns a the product value multiplied by the given values.

Example

package main

import (
	"fmt"

	"github.com/ayonli/goext/mathx"
)

func main() {
	fmt.Println(mathx.Product(1))
	fmt.Println(mathx.Product(1, 2))
	fmt.Println(mathx.Product(1, 2, 0.5))
}

Output:
1
2
1

func Sum

func Sum(values ...float64) float64

Returns the sum value of the given values.

Example

package main

import (
	"fmt"

	"github.com/ayonli/goext/mathx"
)

func main() {
	fmt.Println(mathx.Sum(1))
	fmt.Println(mathx.Sum(1, 2))
	fmt.Println(mathx.Sum(1, 2, 0.5))
}

Output:
1
