Complex numeric display format

[TiTou]

Hi all,

By default when we drop a complex numeric indicator (CSG, CDB or CXT) it displays the complex number are Re/Im

Is there a way to change to display format to display the complex number as r/theta?

Cheers

I don't think so, but you can always use a string indicator and do whatever you want with the parts. 😄

Or even do degrees. 😉

Ah well... Thanks for confirming what I was fearing.

I'll check if there is not already an idea in the exchange for this, and post one if not.

Of course having a complex control with R/theta is a bit more complicated.

On a tangential discussion, complex numbers are always internally represented as two floating point values RE/IM, while under certain applications it would be more useful if these two numbers would represent R/theta. Imagine that the complex number represents the direction and speed of a vehicle. As soon as the vehicle stops temporarily (speed=0) all direction information is currently irreversibly lost (RE=IM=0), even though it is still pointing in a very defined direction. With R/theta, the direction could be maintained. Currently, we need to program around that :).

I doubt that LabVIEW would invent its own formatting codes. It might be worth searching the web if there is already prior art in other programming languages.

Hehe
My use case is more power grid than navigation, but yes, it would be helpful.
