  floats code
  My document starts with\documentclass{sig-alternate} \usepackage{listings}and it includes listings like this:\begin{lstlisting}[label=samplecode,float=tb,caption=My super code] // code \end{lstlisting}I also tried frame=tb. However, the listing is placed as flow-text right in the surrounding text. It’s not floating. I also tried including the float package, didn’t help either.PS There are figures and tables in the document that are placed as floats.EDIT (.log):This is pdfTeX, Version 3.1415926-1.40.10 (TeX Live 2009/Debian) (format=pdflatex 2012.12.23) 22 APR 2013 16:41 entering extended mode%&-line parsing enabled. **paper.tex (./paper.tex LaTeX2e Babel and hyphenation patterns for english, usenglishmax, dumylang, noh yphenation, farsi, arabic, croatian, bulgarian, ukrainian, russian, czech, slov ak, danish, dutch, finnish, french, basque, ngerman, german, german-x-2009-06-1 9, ngerman-x-2009-06-19, ibycus, monogreek, greek, ancientgreek, hungarian, san skrit, italian, latin, latvian, lithuanian, mongolian2a, mongolian, bokmal, nyn orsk, romanian, irish, coptic, serbian, turkish, welsh, esperanto, uppersorbian , estonian, indonesian, interlingua, icelandic, kurmanji, slovenian, polish, po rtuguese, spanish, galician, catalan, swedish, ukenglish, pinyin, loaded.
