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.
