Hi,
I’m in Ignition 8.1.12.
Expression below not works I don’t know why. Result must be 13.8.
No changes. Result still 13 instead of 13.8
I think you’ve got the right function, just the wrong format string. Try #,##0.0, e.g.
1 Like
With “#,##0.0” result is 13.0.
Curious
What if you just return {value} ?
What are the settings under Project->Project Properties and Perspective->General? Do you have a Project Locale specified?
You could use
"{n:1f}.format(n=value)"
What is exactly the output format you want ?
Project Locale is Browser.
With just {value} output is the same as input var type is string.
I’m confused. Does the bare numberFormat({value}) (without toFloat) not work for you?
What’s the actual type of this value (try the typeOf expression function)? It sure looks like a floating point to start.
Wait, what ?
Is your input property a string, or is the output a string ?
input is a string,
and the result is displayed in a label text so output should be a string.
Same problem. 
Can you try doing it on another input and see if you get the same results ?
Maybe make a custom prop and bind it to toString(13.81235124), then try applying the same process to this one.
Is numberFormat supposed to obey the locale? Yours appears to have put a , in instead of a . but I can’t get it to do that for me like the Format Transform can. Unfortunately with the Format Transform I can’t have dynamically set significant figures.
