Using script, the getresult("mode1", "neff"); returns the effective index to 5 decimal places, e.g, 2.14161+1.99136e-11i. In modal analysis, effective index data exported to a text file contains more significant figures, e.g.

f
3.747405725000e+14

effective_index(real),effective_index(imag),loss
2.141613322230e+00,1.991363184436e-11,1.358484420378e-03
2.125338278328e+00,2.536038929807e-11,1.730055774125e-03

Is it possible to change the number of signficant figures? I am hoping to achieve this using script, rather than manually exporting the data file. Thanks

The getresult by default gives short-format data, which has 6 digits in total. The saved data seems using long format to give more digitst. This might be desired for example later those data are used in INTERCONNECT and the component can be very long, say meters or kilimeters. 

You can use

format long;

?getresult("mode1", "neff"); 

and then

format short;

?getresult("mode1", "neff"); 

 

If you want to have short format data, you can write the data into a text file using "write":
