i using openxml creating excel document , want display percentage single decimal place percentage format "85.5%". not able find proper solution this.

following function create stylesheet.

private stylesheet generatestylesheet(numberingformat nf2decimal)     {         return new stylesheet(             new fonts(                 new font(new fontsize() { val = 11 }, new color() { rgb = new hexbinaryvalue() { value = "000000" } }, new fontname() { val = "calibri" }),                 new font(new bold(), new fontsize() { val = 12 }, new color() { rgb = new hexbinaryvalue() { value = "000000" } }, new fontname() { val = "calibri" }),                 new font(new bold(), new fontsize() { val = 11 }, new color() { rgb = new hexbinaryvalue() { value = "fccb02" } }, new fontname() {
