Adding colorful layer called typed constants

Sometime we need extra tools for advance problems like magician or wizard use their magic gown , advance spells . If You see Harry potter in your childhood then you remember. Without type constants everything fine but if you become a master then you know how to use advances tools. if you interested in more examples then visit

             Advance tools                                          Description

1      Typed Constants                                           solve your problem in your style

2.      Untyped Constants                                      use in scientific research

3.      grpc/protobuf                                              scale out your application (microservice)

4.       goroutines                                                   application optimization

5.       packages                                                      application deploy

There Are few advances tools  which add extra layers or enhance application power. There're so many, when a time come i will introduce them.

Problem is that you convert kelvin into celsius. 

package main
	import (
	"fmt"
	)
	type Kelvin float64
	type Celsius float64
	const (
	AbsoluteZeroKelvin Celsius = 273.15
	AbsoluteZeroCelsius Kelvin = 273.15
	)
	func main() {
	var k Kelvin = 1
	var c Celsius = 1
	kelv := KtoC(k)
	cels := CtoK(c)
	fmt.Println("value of kelvin", kelv , "value of celsius", cels )
	}
	func KtoC(k Kelvin) Celsius{
	return Celsius(k - AbsoluteZeroCelsius)
	}
	func CtoK(c Celsius) Kelvin{
	return Kelvin(AbsoluteZeroKelvin + c)
	}

 type Kelvin float64

       First this at package level which means place after import and second it start with Uppercase. If a variable , constants , type declare at package level and start with uppercase then it's means it access other packages too.

 If you write structs in C you know this line create a new type name Kelvin and it's datatype value in float

AbsoluteZeroCelsius Kelvin = 273.15

This is a way to initialize your type, if you want.
Second it's also help you in conversion

func KtoC(k Kelvin) Celsius

In golang func means this is the function

KtoC is the name of the function

k Kelvin here k is a contain-variable of this type

Celsius called return type of a function.

If you look at example functions after return
Celsius(k - AbsoluteZeroCelsius)

this convert back into required datatype.
This is just a flavour of sweet pie,
soon we discuss them in very
details along with other advance tools.

acceleration and tells you

how much force body applied
