Create a numerical unit converter, developed using Golang

Number unit converter is a common tool that can help us convert between different units, such as conversion between length units, conversion between weight units, etc. Today, we will use Golang to develop a numerical unit converter, let's take a look at a specific code example.

First, we need to create a new Golang file named converter.go. In this file, we will define a structure Converter to store information and methods related to the converter.

package main

import (
    "fmt"
)

type Converter struct {
    Value float64
}

func (c Converter) ToMeter() float64 {
    return c.Value * 0.3048
}

func (c Converter) ToFeet() float64 {
    return c.Value / 0.3048
}

func main() {
    c := Converter{Value: 1.0}
    fmt.Printf("1 foot is equal to %.2f meters
", c.ToMeter())

    c = Converter{Value: 1.0}
    fmt.Printf("1 meter is equal to %.2f feet
", c.ToFeet())
}

In this code, we first define a structure Converter, which contains a field Value to store the value to be converted. Then, we define two methods ToMeter and ToFeet, which are used to convert feet to meters and meters to feet respectively. Finally, in the main function, we create a Converter instance, convert feet to meters and meters to feet, and print out the results.

Run the above code, we can see the following output:

1 foot is equal to 0.30 meters
1 meter is equal to 3.28 feet

In this way, we have successfully developed a simple digital unit converter using Golang. Of course, you can extend this converter according to your needs and add more unit conversion methods and functions. Hopefully this example can help you better understand how to develop a numeric unit converter using Golang.
