Whittled superscript sup tag TextView Android issue
Issue: Cropped superscript index between tags sup /sup is not correctly visible in TextView or View as Button.
String s = "10<sup>12 </sup>";
textView.setText(Html.fromHtml(s)); // 12 will cropped
// solution:
s = "10<sup>12 </sup>\t "; // add behind ending of sup tag the tabulator \t,
// but not char \t but only press to TAB key!!! in source code
textView.setText(Html.fromHtml(s)); // 12 is visible correctly

Java double is 64 bit double precision type used when fractional
precision calculation is required.
Java double je datový typ (reálné číslo) o velikosti 64 bitů. Používá se například pro přesný výsledek po dělení za desetinnou tečkou. Pokud nepotřebuje tak veliké číslo použijte raději typ float, šetříte tím paměť mobilního telefonu.
