Limiting export of digits in mlreport.gen.dom*?

I'm using mlreport.gen.dom* to fill calculations into a word template with holes. For example:

hole1=1.535;
hole2=hole1*4000;
import mlreportgen.dom.*;
namethedoc='testing'
type = 'docx';
calltheform='must have a form to run this sample'
rpt = Document(namethedoc,type,calltheform);
open(rpt);
while(~strcmp(rpt.CurrentHoleId,'#end#'))
   switch(rpt.CurrentHoleId)
        case 'Hole1'
             append(rpt,hole1);
        case 'Hole2'
             append(rpt,hole2);
   end
   moveToNextHole(rpt);
end
close(rpt);
docview('testing');

When running this on its own, none of the numbers round when they appear in Word (they report too many decimal points). To combat that, I added a separate rounding.m file for rounding and changed the cases to append(rpt,rounding(dx1)). If the number is small (between 0 and 5), I want several decimal points read out, otherwise, the nearest integer is fine. The function, given below, and several variants have not successfully put the rounded number into the document for the 0 to 5 range. It even takes given values, such as 1.535, and makes it into 1.534999999999999999.

function y=rounding(x)
clc
 if x>0 && x<5
      format short
      y=round(x,5,'significant')
      fprintf('%5.2f',y)
 else
      format short
      y=round(x)
      fprintf('%f',y)
  end
end

I've tried with and without the fprintf and several other variations.

Any ideas about how I can limit the display of digits when copying from MATLAB to Word?

Try this:

import mlreportgen.dom.*
d = Document('FloatingPoint', 'docx');
append(d, Paragraph(rounding(2.129999)));
append(d, Paragraph(rounding(6.5)));
close(d);
rptview(d);

function y=rounding(x)
 if x>0 && x<5
      format short
      y=round(x,5,'significant');
      y = sprintf('%5.2f',y);
 else
      format short
      y=round(x);
      y = sprintf('%0.0f',y);
  end
end

Thank you so much!
