I want to convert numbers With decimal (in currency )to word

ex.: 12345.60 --> twelve thousand three hundred forty-five dollars and sixty cents

i got this code from http://www.csharp-tutorials.info/2016/04/convert-numbers-to-words-in-c.html

``` public static string NumberToWords(int number)
{
if (number == 0)
return "zero";

if (number < 0)
return "minus " + NumberToWords(Math.Abs(number));

string words = "";

if ((number / 1000000000) > 0)
{
words += NumberToWords(number / 1000000000) + " billion ";
number %= 1000000000;
}

if ((number / 1000000) > 0)
{
words += NumberToWords(number / 1000000) + " million ";
number %= 1000000;
}

if ((number / 1000) > 0)
{
words += NumberToWords(number / 1000) + " thousand ";
number %= 1000;
}

if ((number / 100) > 0)
{
words += NumberToWords(number / 100) + " hundred ";
number %= 100;
}

if (number > 0)
{
if (words != "")
words += " ";

var unitsMap = new[] { "zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen" };
var tensMap = new[] { "zero", "ten", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" };

if (number < 20)
words += unitsMap[number];
else
{
words += tensMap[number / 10];
if ((number % 10) > 0)
words += "-" + unitsMap[number % 10];
}
}

return words;
}
```

it work totally fine with integers but if input double.. it shows error

because it only accept int.

I try my best with my knowledge but I cant alter the code to get what i want..

The problem is that you use modulo on doubles, which is (obviously) not allowed. you have to use `Math.Floor(number)` with the given code for the part before the floating point and `number - Math.Floor(number)` for the part after the floating point. The rest is actually given in your code example, just add `"Dollar"` after the part before the floating point and `"cents"` after the part after the floating point. Your code would look somwhat like that:

```    public static string NumberToWords(double doubleNumber)
{
var beforeFloatingPoint = (int) Math.Floor(doubleNumber);
var beforeFloatingPointWord = \$"{NumberToWords(beforeFloatingPoint)} dollars";
var afterFloatingPointWord =
\$"{SmallNumberToWord((int) ((doubleNumber - beforeFloatingPoint) * 100), "")} cents";
return \$"{beforeFloatingPointWord} and {afterFloatingPointWord}";
}

private static string NumberToWords(int number)
{
if (number == 0)
return "zero";

if (number < 0)
return "minus " + NumberToWords(Math.Abs(number));

var words = "";

if (number / 1000000000 > 0)
{
words += NumberToWords(number / 1000000000) + " billion ";
number %= 1000000000;
}

if (number / 1000000 > 0)
{
words += NumberToWords(number / 1000000) + " million ";
number %= 1000000;
}

if (number / 1000 > 0)
{
words += NumberToWords(number / 1000) + " thousand ";
number %= 1000;
}

if (number / 100 > 0)
{
words += NumberToWords(number / 100) + " hundred ";
number %= 100;
}

words = SmallNumberToWord(number, words);

return words;
}

private static string SmallNumberToWord(int number, string words)
{
if (number <= 0) return words;
if (words != "")
words += " ";

var unitsMap = new[] { "zero", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen" };
var tensMap = new[] { "zero", "ten", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" };

if (number < 20)
words += unitsMap[number];
else
{
words += tensMap[number / 10];
if ((number % 10) > 0)
words += "-" + unitsMap[number % 10];
}
return words;
}

As an addon to the above answer, since most of the systems are globalised these days it is important to support multiple currencies and support conversion according to the different way a country recognises decimal groups. I solved it by creating template in a json file for each key currency i wanted to support and then use the code similar to above (without the hardcoding) to read data from template and convert accordingly. eg of template is below, let me know if anyone needs the code.

Json template for USD to words

```    {

Numbers to Words Converter, Convert a number to USD currency and check writing amounts rounded to 2 decimal places. Choose to have words for the numbers in lowercase, uppercase or� How to convert amounts of money, without decimals, to words in US American English? To write an integer number we first must know the place value of each digit. For example, the number 1,234,567 has a 1 in the millions place, a 2 in the hundred thousands, a 3 in the ten thousands place, a 4 in the thousands place, a 5 in the hundreds place, a 6

Your mapping arrays helped inspire this result, but I went a different route to handle the places. Works well for me. It is geared for American currency. There are a couple of extension methods used (viz. RemoveDoubleSpaces(), TryIntParse()) that will need to be accounted for, but what they do is pretty obvious.

```    public static string ToVerbalCurrency(this double value)
{
var valueString = value.ToString("N2");
var decimalString = valueString.Substring(valueString.LastIndexOf('.') + 1);
var wholeString = valueString.Substring(0, valueString.LastIndexOf('.'));

var valueArray = wholeString.Split(',');

var unitsMap = new[] { "", "one", "two", "three", "four", "five", "six", "seven", "eight", "nine", "ten", "eleven", "twelve", "thirteen", "fourteen", "fifteen", "sixteen", "seventeen", "eighteen", "nineteen" };
var tensMap = new[] { "", "ten", "twenty", "thirty", "forty", "fifty", "sixty", "seventy", "eighty", "ninety" };
var placeMap = new[] { "", " thousand ", " million ", " billion ", " trillion " };

var outList = new List<string>();

var placeIndex = 0;

for (int i = valueArray.Length - 1; i >= 0; i--)
{
var intValue = valueArray[i].TryIntParse();
var tensValue = intValue % 100;

var tensString = string.Empty;
if (tensValue < unitsMap.Length) tensString = unitsMap[tensValue];
else tensString = tensMap[(tensValue - tensValue % 10) / 10] + " " + unitsMap[tensValue % 10];

var fullValue = string.Empty;
if (intValue >= 100) fullValue = unitsMap[(intValue - intValue % 100) / 100] + " hundred " + tensString + placeMap[placeIndex++];
else if (intValue != 0) fullValue = tensString + placeMap[placeIndex++];
else placeIndex++;

}

var intCentsValue = decimalString.TryIntParse();

var centsString = string.Empty;
if (intCentsValue < unitsMap.Length) centsString = unitsMap[intCentsValue];
else centsString = tensMap[(intCentsValue - intCentsValue % 10) / 10] + " " + unitsMap[intCentsValue % 10];

if (intCentsValue == 0) centsString = "zero";

var output = string.Empty;
for (int i = outList.Count - 1; i >= 0; i--) output += outList[i];
output += " dollars and " + centsString + " cents";

return output.RemoveDoubleSpaces();
}
```
