This is what I got based on your inputs and it serves my purpose. Thanks for helping out!

static int formatDoubleToAscii(double d, int bytesToUse, int minPrecision, byte in[], int startPos) {

        int d1 = (int)(d * Math.pow(10, minPrecision));

        String t = String.format("%0"+bytesToUse+"d", d1).toString();
        System.out.println("d1 = "+ d1 + " t="+ t + " t.length=" + t.length());

        for(int i=0 ; i
