Many of us using graphical programming for scientific applications, where we dealing with numbers, measurements, etc.
How often we grab to Windows Calculator to compute simple equations?
What about ability to enter something like 3,75*2,8 into any constant or control (in principle everywhere where we can put numbers) and then get computation result in this place:
In the past I've worked in desktop publishing industry and using the software called "Macromedia Freehand MX", and that was really "killer feature", which saves huge amount of time.
This is how it works:
Or for example, 5 rotated copies:
Even in Color mixer simple computations are allowed:
Everywhere where I can put some numbers, in any dialog:
So, my suggestion to have the same in every numeric control or constant.
This is what I mean:
So, it should be allowed to enter here something like "3*5" or "42+3*5"
As MVP suggested to have the only (at least) base operations *, /, +, -, also combined as shown above, but may be "advanced" support (like fully offered by Formula String) is also not so bad, why not:
Anyway it should work everywhere, including constants on the Block Diagrams:
Also, for example, on Resize Objects Dialog:
Or even in the Settings (in general everywhere for any numeric field across whole LabVIEW):
And also in Run-Time, of course, not only in Development Environment.
If you think that "always enabled" feature will be annoying, then I can suggest to make this optionally per Control/Constant Option:
Or may be as global setting in the Options.
