  24     ECMA Section:       15.1.2.3 Function properties of the global object:
  25                         parseFloat( string )
  26
  27     Description:        The parseFloat function produces a number value dictated
  28                         by the interpretation of the contents of the string
  29                         argument defined as a decimal literal.
  30
  31                         When the parseFloat function is called, the following
  32                         steps are taken:
  33
  34                         1.  Call ToString( string ).
  35                         2.  Remove leading whitespace Result(1).
  36                         3.  If neither Result(2) nor any prefix of Result(2)
  37                             satisfies the syntax of a StrDecimalLiteral,
  38                             return NaN.
  39                         4.  Compute the longest prefix of Result(2) which might
  40                             be Resusult(2) itself, that satisfies the syntax of
  41                             a StrDecimalLiteral
  42                         5.  Return the number value for the MV of Result(4).
  43
  44                         Note that parseFloate may interpret only a leading
  45                         portion of the string as a number value; it ignores any
  46                         characters that cannot be interpreted as part of the
  47                         notation of a decimal literal, and no indication is given
  48                         that such characters were ignored.
  49
  50                         StrDecimalLiteral::
  51                         Infinity
  52                         DecimalDigits.DecimalDigits opt ExponentPart opt
