How to convert double to decimal (2 places)

P: n/a
How do I do this: result needs to be a decimal to 2 places? I get casting
problems on the below:

double myPrice = 1200.125;double myShares = 354.288;

decimal myTotal;

myTotal = myPrice * myShares;

Thanks,

My original code snippet would not complie on VS2005, I would get casting
errors: where as this works:

double myMoney = 1200.125;
double myShares = 354.388;
decimal myTotal = 0.00m;

myTotal = Convert.ToDecimal(myMoney * myShares);

You're code also works:

myTotal = (decimal)(myPrice * myShares);

However in both cases the results are to 4 decimal places instead of 2. Any
ideas?

Use the Math.Round method to round the value after the calculation.

You should also consider to keep the value without reducing the
precision, and round the value when you convert it to a string to
display it. (If you do.)

Thanks...It's for an accounting system so the results need to always stay at
2 decimal places and are stored in a database.
