Round Function

So I am trying to use the round function. From the expression editor function list is says

Round(x[,d])

The issue is when I type this in I get an invalid expression (1519)

I am sure I don't have something correct with the syntax, but can't figure it out. Anybody else run into this problem.

Figured it out. Instead of Round(x[,d])

it's Round(x,d).

Not sure why the square brackets are listed.

Hi Dennis,

square brackets indicate optional arguments in VB documentation notation. So you can type both Round(x) and Round(x, d)

Hey David,

I was wondering if d could be integrated to the round component? I was happy to see the round component. But I do not use it (most of the time), because the d is important.

Best Regards

ps.: hope you had some fun in Berlin :-)

Apologies for being stupid bu could you tell me what wrong with this? Doesn't appear to round. I'm very new to all this

I think you need to set the variable a = math.round() result. Right now you are just setting a = to the original values inputted.

Something like this

RoundValue = math.round(x,2)

A= RoundValue

Syntax for grasshopper expressions and Visual Basic code is different. In this case, the function doesn't do anything because you do not store the return value. It should read:

x = Math.Round(x, 2)

Print(x)

A = x
