How To Calculate Rate of Change (ROC) in Go?

@creola.ebert 

To calculate the rate of change (ROC) in Go, you can follow these steps:

1. Determine the initial value (old value) and the final value (new value) of the quantity you want to calculate the rate of change for.
2. Subtract the initial value from the final value to find the change in quantity. This can be done using the following formula: change = new value - old value
3. Divide the change in quantity by the initial value to get the rate of change. The formula for calculating ROC is: ROC = (change / old value) * 100
4. Multiply the result by 100 to convert it to a percentage.

Here is a simple example code snippet in Go to calculate the rate of change:

package main

import (
	"fmt"
)

func main() {
	oldValue := 50
	newValue := 70

	change := newValue - oldValue
	roc := float64(change) / float64(oldValue) * 100

	fmt.Printf("Rate of change: %.2f%%
", roc)
}

In this example, we are calculating the rate of change between an initial value of 50 and a final value of 70. The output will be:

1

Rate of change: 40.00%

You can modify this code to calculate the rate of change for different sets of values as needed.
