@decimal no longer rounds

Is this intentional? As per the manual, @decimal is failing to round.

Here's an example:

var v as double = 1.228
writeln(@decimal(v,2))

1.23

but instead, I'm getting

1.22

Am I missing something? Do I need to start using @round to get my money values correct?

Thanks,

Steve

No, you are not missing something. @Decimals was not supposed to round, but it did. So it got documented that it did. It was supposed to truncate (so as to be different from @round). The documentation will have to catch up (my fault...sorry. I miscommunicated to our technical writers). If you prefer rounding, use @round.

Thanks, Mark.

I had been using @decimals for displaying and printing money values, but I will switch to @round instead.

Happy Holidays to you and your family!

Bear in mind that whereas @Decimals() returns a string value, @Round() returns a number. So if putting this in a text string you're probably going to want to wrap an @Str(), or an @Decimals(), around the @Round.

Eg:

vNumberString = @Str(@Round(MyNumber,2))

Thank you, Alec.

I would not have thought to do that.

Happy Holidays!

Actually, Alec brings up a good point. If your LE is not formatted to two decimal places (or is a string LE) you might want to run the number through both @round (to round it) and @decimals (to set it to be a numeric string with the appropriate number of decimal places).

Another good point.

Thank you both.
