Hi Maurice,

the square brackets mean the second argument is optional.

So, use:

Round(x)

to round to whole numbers. Or use:

Round(x, 4)

to round to 4 decimal places.

Hi David,
so it's very obvious that "[]"means things inside it are optional.Thanks for this information.

But how to use "Substring(s,i[,L])"??I tried,and with no luck.I think I miss something very obvious/essential.

Sorry, there is a bug in SubString, if you specify the optional third parameter it will always crash. I just fixed it, but it will be a while until the next version comes out.

I just thought the problem was at the bottom of the To-Do list :)

There's a To-Do tree now. I dumped the list when we switched to 0.6.
It's a bit more flexible but I do sometimes get lost in the branches.

You have to keep pruning the tree so it stays pleasantly bonsai size, otherwise it will grow into a mighty oak (which, in this horticultural analogy, would be a bad thing).

Hi David

I'm trying to do something similar but it's rounding the number up to the nearest 1000.

Do you know how to go about this?

Many thanks

Dave

Yup, three steps:

1. Multiply your value by 0.001 (ie. one over thousand)
2. Round this value.
3. Use the Ceiling output of the Round component and multiply that number by 1000

Many thanks David. That's a great help
