#### 13.10.8 Source blocks in LaTeX export

The LaTeX export back-end can make source code blocks into floating objects through the attributes ‘`:float`’ and ‘`:options`’. For ‘`:float`’:

‘`t`’

  Makes a source block float; by default floats any source block with a caption.

‘`multicolumn`’

  Spans the source block across multiple columns of a page.

‘`nil`’

  Avoids a ‘`:float`’ even if using a caption; useful for source code blocks that may not fit on a page.

    #+ATTR_LATEX: :float nil
    #+BEGIN_SRC emacs-lisp
      Lisp code that may not fit in a single page.
    #+END_SRC

The LaTeX export back-end passes string values in ‘`:options`’ to LaTeX packages for customization of that specific source block. In the example below, the ‘`:options`’ are set for Minted. Minted is a source code highlighting LaTeX package with many configurable options.

    #+ATTR_LATEX: :options commentstyle=\bfseries
    #+BEGIN_SRC emacs-lisp
      (defun Fib (n)
        (if (< n 2) n (+ (Fib (- n 1)) (Fib (- n 2)))))
    #+END_SRC

To apply similar configuration options for all source blocks in a file, use the `org-latex-listings-options` and `org-latex-minted-options` variables.
