C # Convert int to currency string with decimal places

Question

Conversions. Blah ... perhaps the most confusing aspect of the language for me.

Anyway, I want to convert int 999 to $ 9.99. Using ToString ("C") gives me $ 999.00, which is not what I want.

All my integers will work this way, if the price of something is 12.30, the int value will be 1230. Two decimal places always. I know that it will be easy for most, I can not find anything here or through Google.

Also, any resources that you have during conversions will be very grateful!

Answer 1

If your source variable is declared as int, then one of the possible solutions is to divide by "100 m" instead of "100". Otherwise, it will perform integer division. eg:

int originalValue = 80; string yourValue = (originalValue / 100m).ToString("C2"); 

This will set yourValue to $ 0.80. If you do not specify "m", it will set the value to "0.00".

NOTE. "m" tells the compiler to treat 100 as a decimal number, and an implicit conversion will occur with originalValue as part of the division.

Answer 2

Just divide by 100:

 yourValue = (originalValue / 100).ToString("C");<br> // C will ensure two decimal places... <br> // you can also specificy en-US or whatever for you currency format

See here for more details.

UPDATE:

Today I have to be troubled ... you will also have to convert to double or you will lose decimals:

 yourValue = ((double)originalValue / 100).ToString("C"); 

(Alternatively, you can use decimal, since this is usually the preferred type for the currency ).

Answer 3

I have a function for those who just need to split zeros based on a specific separator. For example: 1250000 → 1,250,000 ..

 public static string IntToCurrencyString(int number, string separator) { string moneyReversed = ""; string strNumber = number.ToString(); int processedCount = 0; for (int i = (strNumber.Length - 1); i >= 0; i--) { moneyReversed += strNumber[i]; processedCount += 1; if ((processedCount % 3) == 0 && processedCount < strNumber.Length) { moneyReversed += separator; } } string money = ""; for (int i = (moneyReversed.Length - 1); i >= 0; i--) { money += moneyReversed[i]; } return money; } 

Enjoy it!
