using string.fomat to round to two decimal places

I am splitting a decimal value into dollars and cents

Dollars = Math.Truncate(Total);
Cents = Total - Dollars;

How can I use string.format to get the Cents variable to display just two digits so

DOLLARS = 1343
CENTS = 00

Currently I get  CENTS = 0.0000

And what's the Total ? It looks right your code.

I think it maybe that CENTS is a decimal variable?

If you have defined the variables as decimal (or double) and the Total is something like 1343.12 then you will have 0.12 in the Cents.

Yes thanks  but I just want the cents to be displayed as  12  and not 0.12

You can use formatting to scale a number down, but not up.

Scale the cents value up by two decimals when you calculate it:

Cents = Math.Round((Total - Dollars) * 100);

Then you can use the format string "00" if you want to display it as two digits:

string price = String.Format("{0} dollars and {1:00} cents", Dollars, Cents);

That's another point and you can do as GreenGhost suggested

Thanks but if I use the method above and pass in zero I get the error

Index (zero based) must be greater than or equal to zero and less than the size of the argument list

Why not use the following
cents = (0.12).tostring.split(".")(1)

You would have to specify the culture used for formatting the value into a string. Some cultures format that value into "0,12", which would make the split fail.

@GreenGhost,
Agreed but mugsey appears to be from Britain so it suggested that method.

@CodeCruiser,

Yes, but his server might be hosted in Sweden...

Besides, other people will also take advice from the answers, and they can live anywhere. They may also use it in a windows application, then the culture is dependent on who's running the program, which might come as a nasty surprise...

That's why I wanted to clarify the possible culture issues with the suggestion. :)
