   File Name:          15.1.2.3-2.js
   ECMA Section:       15.1.2.3 Function properties of the global object:
   parseFloat( string )

   Description:        The parseFloat function produces a number value dictated
   by the interpretation of the contents of the string
   argument defined as a decimal literal.

   When the parseFloat function is called, the following
   steps are taken:

   1.  Call ToString( string ).
   2.  Remove leading whitespace Result(1).
   3.  If neither Result(2) nor any prefix of Result(2)
   satisfies the syntax of a StrDecimalLiteral,
   return NaN.
   4.  Compute the longest prefix of Result(2) which might
   be Resusult(2) itself, that satisfies the syntax of
   a StrDecimalLiteral
   5.  Return the number value for the MV of Result(4).

   Note that parseFloate may interpret only a leading
   portion of the string as a number value; it ignores any
   characters that cannot be interpreted as part of the
   notation of a decimal literal, and no indication is given
   that such characters were ignored.
