I'm looking for something that will get me this result.
I've started to 'write' it with SM parts but it's getting much more complex than I think it should be.
Anybody got a bright idea how to do this within SM?
Any chance this is coming as a primative?
p.s. - not merely looking to 'round' but to allow '3.013' to show '3.0' if decimal is set to 1 (and not show '3')

OK - so I found this in another thread. One day I'll learn how to search this forum effectively before I post. 😈
Jorge asked the use of it would be.
It's for display purposes - that's why in my sleep deprived condition I posted what looks like a math question in the graphics from.
I'd like to be able to display the current decimal value of a parameter without it jumping around as it drops zeros from the back end of the string or without showing 7 decimal places when in most cases 2 or 3 is plenty.

We can probably make a very low-level component for string formatting based on the standard c/c++ format specifications. Very easy and has been on our todo list for some time.
You'd need to use the format specifications as outlined here: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vccore98/HTML/_crt_format_specification_fields_.2d_.printf_and_wprintf_functions.asp
To get 3 decimal places all you'd need to do is use ".3f" as the format specification meaning (the f means floating point).

Unfortunately there's no way to _increase_ the number of decimals currently shown, but we can atleast set them to any number below that by doing some integer "tricks".
oddson ·
Problem with 'tricks' is zero's are still dropped from the display from floats - no matter what you do (or at least no matter what I did).
3.4 to 3 decimals is still 3.4 not 3.400
I played around last night with string manipulations until it got so complex I just gave up.

Don't waste any more time on workarounds oddson - new component in the next release 🙂
oddson ·
When most developers say "it's in the next release" you get ready for a long wait - you guys seem to release about twice a week. 😀
oddson ·
More than I hoped for and faster too. What was that 2 days? 😮
I love that I can have string content after the format!
I see there's some bugs but I'm still impressed. 😀
Some documentation would be great (as always) but I'll use printf() documentation from the link above for now.
Thanx! 🙂 😀 😉

You know, I'm still not sure what & what isn't included from Microsoft's docs in Format... can someone make a handy summery chart please? cheers

Try this... I'm assuming they're doing an sprintf underneath.

ahhh, much easier to read; thanks!

Given many reports of instability in the Format String primitive I have wrapped it in a module to produce the original intended result of a fixed decimal string.
formatFloat.osm

That's handy; thanks.
Could someone make an all-options-inclusive version that any (float atleast) formating that can be done with the Format String be selected via GUI please? Like how the Label primitive has the Font & Format preferences that gives the user all options visually via the GUI.
What I was really looking for is an output like this: +1 +.75 +.5 0 -.25 -1 But I'm sure in the future I'd want some other funky formatting.
I personally prefer the module to have an output of a String value to be connected to the Format String on the outside, feeding the 2nd input. That way, one can feed a String, then remove the module when you're happy with the formatting. cheers!

You mean every quarter of unit? I did it, I'll search and post...

formatString.osm
Does as much of the formatting as you'd likely want with a float and the format string generator is purged when compiled to VST.

This is really useful Oddson.
I have noticed however that if you have the + checked and you feed the module a value of zero the output is "+0". Not sure what to do about that as I can't get my head round this formatting stuff at all. Any ideas?
BasherT ·
After hours trying to get to grips with the intricacies of the format codes, I came up with a solution to this by using a simply switch to change the format to one that does not show the sign when the value equals zero!

There is a difference between +0 & -0. But for what I used it for, I didn't like it. So I think I connected the output to either a Float or String primitive to get rid of it... I forget, maybe both?
