      In particular, scientific notation is handled gracefully: e -> 10^
  
      Parameters
      ----------
      x : `float`
          the number to represent
  
      format : `str`, optional
          the output string format
  
      Returns
      -------
      tex : `str`
          a TeX representation of the input
  
      Examples
      --------
      >>> from gwpy.plot.tex import float_to_latex
      >>> float_to_latex(1)
      '1'
      >>> float_to_latex(2000)
      '2\times 10^{3}'
      >>> float_to_latex(100)
      '10^{2}'
      >>> float_to_latex(-500)
      r'-5\!\!\times\!\!10^{2}'
