Add rounding to this script

Question

Hi everyone,
I need to add rounding to this script. I need two versions, one for 1 decimal place and one for 0 decimal places. Can anyone help out?
#target illustrator
addMeasurements();
function addMeasurements() {
    var i, doc, imp, met, txtItems, txt, nub;
    doc = app.activeDocument;
    imp = doc.layers.getByName( 'Text' );
    met = doc.layers.add();  met.name = 'New';
    txtItems = imp.textFrames;
    for ( i = 0; i < txtItems.length; i++ ) {
        txtItems[i].duplicate( met, ElementPlacement.PLACEATEND )
    txtItems = met.textFrames;
    for ( i = 0; i < txtItems.length; i++ ) {
        var nub = parseInt( txt = txtItems[i].contents ); // For Numbers only!!!!
        txtItems[i].contents = String( txt * 1.1 )
Thanks in advance.

The example is just a basic function… Just place it after the main function body in your script… Call it where you need it… here is an example… I changed your parseInt() to parseFloat() to deal with your decmial values… While this should wolk it still may NOT be what you want… i.e. it does nothing about keeping the alpha characters in your text frames the new numbers replace all content…
#target illustrator
addMeasurements();
function addMeasurements() {
    var i, doc, imp, met, txtItems, txt, nub;
    doc = app.activeDocument;
    imp = doc.layers.getByName( 'Numbers' );
    met = doc.layers.add();  met.name = 'New';
    txtItems = imp.textFrames;
    for ( i = 0; i < txtItems.length; i++ ) {
        txtItems[i].duplicate( met, ElementPlacement.PLACEATEND )
    txtItems = met.textFrames;
    for ( i = 0; i < txtItems.length; i++ ) {
        var nub = parseFloat( txtItems[i].contents ); // now parseFloat()
                              nub = nub * 1.123456; // just to check the function rounds…
                              var rnub = roundToDP( nub, 2 );
        txtItems[i].contents = String( rnub ); // replaces all content…?
function roundToDP( n, dP ) {
          return Math.round( n * Math.pow( 10, dP ) ) / Math.pow( 10, dP );
