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.
