HP34401A output Data to float

[smoken]

Currently using HP34401A driver and use the example code to display the result of the reading.

Data Type declaration of the variables according to the sample
            ViReal64  reading;
            ViChar    msgStr[256];

checkErr( hp34401a_Read (hp34401a, 5000, &reading));
sprintf (msgStr, "%f", reading);

so for it to display on the panel, i created

SetCtrlVal(panel,PANEL_STRING, msgStr);

not it shows the reading on the Panel as a string(correct me if I am wrong),
because I want to do a calculation first on the reading like I want to display it on float, how can i convert it as such, something like
floatvariable = reading/somevalue;
SetCtrlVal(panel,PANEL_STRING, floatvariable);

thanks

edit: can someone  move this to Labwindows/CVI Area?
