converting Number Value to string

[jstraub78]

Hello,

What's the easiest rule/function for converting the value from a number rule to a string?

For example, I have...

Rule DoorWidth As Number = 21

What I would like end up with is an additional rule like this, based off of the DoorWidth value:

Rule DoorWidthString As String = "21"

I'm just trying to convert a numerical value, evaluated from a rule, to a string.  I know this can be done with :Name rules, by using the MakeString function, but I'm not sure how to change the value of a numerical rule to a string.

I imagine I'm missing something obvious.

Thanks!

Joe

Nevermind,

It looks like the "StringValue" function is what I was looking for. 

Well, now I know 🙂

You can also use format(%d,expression) or format(%g,expression). %d will round a number to an integer, whereas %g will keep it a decimal.

Thanks, that could be handy as well!

Hi,

Be aware that stringvalue is not intended to reliably format the output.

For that you use the format function which uses C like notation, such as

Intent >format("my number is %g",2.301)
--> "my number is 2.301"
Intent >format("my number is %3.2g",2.301)
--> "my number is 2.3"
