math.SqrtPhi Constant

The SqrtPhi constant is an inbuilt constant of the math package which is used to get the square root of the mathematical constant φ (Golden Ratio), approximately equal to 1.2720196495.

Syntax:

float64 math.SqrtPhi

Parameter(s):

  • None

Return Value:

The return type of math.SqrtPhi constant is float64, it returns the square root of the mathematical constant φ (Golden Ratio).

Example 1:

// Golang program to demonstrate the
// example of math.SqrtPhi Constant

package main

import (
	"fmt"
	"math"
)

func main() {
	fmt.Printf("Type of math.SqrtPhi is %T\n", math.SqrtPhi)
	fmt.Println("Value of math.SqrtPhi:", math.SqrtPhi)
}

Output:

Type of math.SqrtPhi is float64
Value of math.SqrtPhi: 1.272019649514069

Explanation:

In the above program, we imported the math package to use the math.SqrtPhi constant, then printed the type and value of the math.SqrtPhi constant.

Example 2:

// Golang program to demonstrate the
// example of math.SqrtPhi Constant

package main

import (
	"fmt"
	"math"
)

// creating function to
// return the value of SqrtPhi.
func getSqrtPhi() float64 {
	return math.SqrtPhi
}

func main() {
	fmt.Println("Value of math.SqrtPhi:", getSqrtPhi())
}

Output:

Value of math.SqrtPhi: 1.272019649514069
