This project is to provide diabetics with faster counting of products and finding them, it will allow you to forget about searching a notebook with stored products and save us from mistakes in calculations. All these factors are supposed to improve the quality of life of the user and help him maintain balanced diabetes.

There are probably many different calculation methods, those that have been implemented in this application are tested and used by me on a daily basis.

When it comes to carbohydrate exchangers, the matter is very simple. The user gives us carbohydrates and we divide them by 10.

fun carbohydrateExchanges(carbohydrates: Double): Double {
        return roundToOneDecimal(carbohydrates / 10)
}

In the case of calculating the protein and fat exchangers, we have two options:

• The first option is to calculate the protein and fat values, multiply protein by 4 and fat by 9, add the results together and divide by 100.

fun proteinFatExchangers(protein: Double, fat: Double): Double{
        return roundToOneDecimal((protein * 4 + fat * 9) / 100)
}

• The second option is to calculate from the caloric value of the product. Subtracting the carbohydrates multiplied by 4 and dividing the result by 100, this is a faster procedure considering it only requires carbohydrate and caloric values.

fun proteinFatExchangersByCal(cal: Double, carbohydrates: Double): Double{
        return roundToOneDecimal((cal - (carbohydrates * 4) ) / 100)
}

ℹ The end result of the calculation is rounded up to one decimal place.
