   I wrote a CustomGui for Real to allow input of more decimal places because I need this occasionally in my plugins.

Since this might be interestion for you folks so I decided to share the code here.

Theres a little limitation tho: Currently it doesnt use the UNIT set in the description. Is there an easy way to find out which unit is set? (so i can append it to the string)

looks like this:

Thanks. Generous to share. I always simply use percentage fields so I can support more digits but this is also nice.

Usually you use FormatNumber() which will give you a string with the current unit attached but you can also read out the units from the preferences and do it yourself (or add your own units). That´s what I did for my real customgui. Here is a code snippet:

Awesome, thank you, Katachi!

I'll add it to my code tomorrow.

Looks like I can't append a unit string. As soon as enter a value smaller than 0.001 with a unit string appended ("m", for example), C4D apparently parses the whole thing wrong and throws weird numbers at me.

I'm not going to spend any more time on this - but if someone figures it out, please let me know

Does this code really work for you? For me it doesn´t do anything. The value doesn´t even change and element->GetReal(ID) does always return the initial value.

ok, ok, my fault. It works but you need to get rid of this line:

The problem with the unit appending is that c4d tries to interpret the appended unit as the unit that is currently set in the c4d preferences.
