Return double value NAN from CVI code module

When I return the value NAN from a CVI function in a DLL used as a code module, TestStand displays it as IND. I'm thinking the conversion is a feature of the CVI adapter.

I want it to show as NAN in my report. Will I have to do some manipulation to get that result?

Simple CVI function

#include <math.h>

void ReturnNAN(double *val)
{
	*val = NAN;
}

According to CVI's help for C99 extensions,  NAN is a quiet NAN.

According to TestStand's help for special constant values, NAN is a quiet NAN, and IND is a Signaling NAN.

I'm using TestStand 2010 SP1 and CVI 2010. Could someone check this with TestStand 2013 and CVI 2013 for me?

Edit: I just tested with the C/C++ adapter, and I get the same behavior.

Edit 2: I just tested changing the sign of the return value (i.e. *val = -NAN). The value is still displayed as IND
