Bleed settings added with script not correct

[schroef]

When we use JSX to save a pdf and set the bleed, bleedOffsetRect, we use points. This value is an Array of 4 doubles. I have a made a custom dialog to export PDF with custom settings. I use a script to take the bleed, which i input in a unit used in the document. Then i have a function to convert cm unit to points. At first it returns a float value with a number about a 15 decimal number. This number is correct when i did a double check. But when i open the PDF, the value seems to have been rounded.

To double-check this when i convert 1 cm to points it returns 28.3464566929134 pt this value should give a bleed of 1cm. But when i open the document, it has a bleed of around 0.9875.

function to convert to pt

function convertToUnit(value, unit) {
    switch (docRef.rulerUnits) {
        case RulerUnits.Picas:
            value = new UnitValue(value, "pc").as(unit);
            break;
        case RulerUnits.Inches:
            value = new UnitValue(value, "in").as(unit);
            break;
        case RulerUnits.Millimeters:
            value = new UnitValue(value, "mm").as(unit);
            break;
        case RulerUnits.Centimeters:
            value = new UnitValue(value, "cm").as(unit);
            break;
        case RulerUnits.Pixels:
            value = new UnitValue(value, "px").as(unit);
            break;
        case RulerUnits.Points:
            value = new UnitValue(value, "pt").as(unit);
            break;
        default:
            value = new UnitValue(value, unit).as(unit);
    }
    return value;
    // return Math.round(value);
};

// cm rulers
// alert(Number(convertToUnit(1, "pt")))

// pt rulers
// alert(Number(convertToUnit(28.3464566929134, "cm")))
alert(Number(convertToUnit(28, "cm")))

When i hardcode the value of 28 points in the pdf exporter, i get exactly what im getting when i used my scripted version with inout values. It seems it only takes integer number. One document i read it said it takes an Array of doubles, other simply state a Number.

the UnitValue units are switched, it should be like this for points

case RulerUnits.Points:
value = new UnitValue(value, unit).as("pt");

instead of 

case RulerUnits.Points:
value = new UnitValue(value, "pt").as(unit);

That's is weird. When I used a test document using cm as rulers and I call it using 1 as unit. I get back 28.346.... which is the correct amount in points

I'll try your post nted version as well, see what happens

Ps the example which is uncommented, inputs as points and returns as cm. This one works when document is in points
