How to format and print data with currency symbols and precision in Go?

To format and print data with currency symbols and precision in Go, you can use the sprintf function from the fmt package along with the golang.org/x/text/currency package. Here's an example code:

package main

import (
	"fmt"
	"golang.org/x/text/currency"
)

func main() {
	amount := 1234.5678

	// Get currency formatter for a specific currency
	formatter := currency.Symbol(currency.USD).Narrow()

	// Format the amount with currency symbol and precision
	formattedAmount := fmt.Sprintf("%s%.2f", formatter, amount)

	// Print the formatted amount
	fmt.Println(formattedAmount)
}

In this code, we first import the required packages: fmt for sprintf function and golang.org/x/text/currency for currency symbol formatting.

Next, we define the amount that needs to be formatted.

To get the currency formatter, we specify the currency symbol using currency.Symbol and call the Narrow method to get the format with currency symbol and precision.

Then, we use fmt.Sprintf to format the amount with the currency symbol and precision. The %s is used for the currency symbol placeholder and %.2f specifies that we want the amount to be formatted with 2 decimal places.

Finally, we print the formattedAmount to see the result.

Output:

$1234.57

Note: Make sure to add the golang.org/x/text package to your go.mod file or use go get golang.org/x/text to install it before running the code.
