9 ECMA Section: 15.1.2.3 Function properties of the global object:
10 parseFloat( string )
11
12 Description: The parseFloat function produces a number value dictated
13 by the interpretation of the contents of the string
14 argument defined as a decimal literal.
15
16 When the parseFloat function is called, the following
17 steps are taken:
18
19 1. Call ToString( string ).
20 2. Remove leading whitespace Result(1).
21 3. If neither Result(2) nor any prefix of Result(2)
22 satisfies the syntax of a StrDecimalLiteral,
23 return NaN.
24 4. Compute the longest prefix of Result(2) which might
25 be Resusult(2) itself, that satisfies the syntax of
26 a StrDecimalLiteral
27 5. Return the number value for the MV of Result(4).
28
29 Note that parseFloate may interpret only a leading
30 portion of the string as a number value; it ignores any
31 characters that cannot be interpreted as part of the
32 notation of a decimal literal, and no indication is given
33 that such characters were ignored.
