GetProperty question

[Chicagoan2016]

In our reports, we show decimal values to two decimal places. Our Csla objects have decimal properties that return decimal values to four places. We just use something like Math.Round() but I was wondering if we could use a variation of GetProperty?

If you need the business object to keep the value with extra decimals, and only need to round for the report, I would do the rounding in the report code. If you want the business object to only have the value with two decimals, I would use a business rule to enforce that. It is common for our business objects to have a DecimalPlaces rule (a custom rule we created). If you need both values, you could have two properties and apply a rule similar to DecimalPlaces on the extra property. You would need to be careful that you are using the appropriate property in each usage context.

Thanks @hurcane, like you said we could use the report code.
Our objects that we feed to SSRS are read only objects (and collections) so can't use a custom rule (not that I am aware of).

Decimals can get tricky. You need to ask whether the truncated/rounded values are important visually in the report, or tangibly for calculations. Early in my career I did a bunch of work where decimals and rounding mattered for financial and inventory reports, and it was an effort to make sure the right precision was stored in the fields in memory and the database.

You don' want an "Office Space" scenario with those fractional pennies 😉
