  42    ECMA Section:       15.1.2.3 Function properties of the global object:
  43    parseFloat( string )
  44
  45    Description:        The parseFloat function produces a number value dictated
  46    by the interpretation of the contents of the string
  47    argument defined as a decimal literal.
  48
  49    When the parseFloat function is called, the following
  50    steps are taken:
  51
  52    1.  Call ToString( string ).
  53    2.  Remove leading whitespace Result(1).
  54    3.  If neither Result(2) nor any prefix of Result(2)
  55    satisfies the syntax of a StrDecimalLiteral,
  56    return NaN.
  57    4.  Compute the longest prefix of Result(2) which might
  58    be Resusult(2) itself, that satisfies the syntax of
  59    a StrDecimalLiteral
  60    5.  Return the number value for the MV of Result(4).
  61
  62    Note that parseFloate may interpret only a leading
  63    portion of the string as a number value; it ignores any
  64    characters that cannot be interpreted as part of the
  65    notation of a decimal literal, and no indication is given
  66    that such characters were ignored.
