The <sup> HTML element can be used to place text in this form:

2<sup>3</sup>

Turns: 2 3 .

Alternatively, you can use Unicode characters for superscript (although only a few are supported):

2&#x00B3;

2³. In this case it would be necessary to map each number of 0 to 9 to its corresponding code point .

If you have this value in a string as you put it, you can do this:

var x = '2,5';
var partes = x.split(',');
var htmlString = partes[0] + '<sup>' + partes[1] + '</sup>';
