+ 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.
