ECMA Section: 15.1.2.2 Function properties of the global object
parseInt( string, radix )
Description:
The parseInt function produces an integer value dictated by intepretation
of the contents of the string argument according to the specified radix.
When the parseInt function is called, the following steps are taken:
1. Call ToString(string).
2. Compute a substring of Result(1) consisting of the leftmost character
that is not a StrWhiteSpaceChar and all characters to the right of
that character. (In other words, remove leading whitespace.)
3. Let sign be 1.
4. If Result(2) is not empty and the first character of Result(2) is a
minus sign -, let sign be -1.
5. If Result(2) is not empty and the first character of Result(2) is a
plus sign + or a minus sign -, then Result(5) is the substring of
Result(2) produced by removing the first character; otherwise, Result(5)
is Result(2).
6. If the radix argument is not supplied, go to step 12.
7. Call ToInt32(radix).
8. If Result(7) is zero, go to step 12; otherwise, if Result(7) < 2 or
Result(7) > 36, return NaN.
9. Let R be Result(7).
10. If R = 16 and the length of Result(5) is at least 2 and the first two
characters of Result(5) are either "0x" or "0X", let S be the substring
of Result(5) consisting of all but the first two characters; otherwise,
let S be Result(5).
11. Go to step 22.
12. If Result(5) is empty or the first character of Result(5) is not 0,
go to step 20.
13. If the length of Result(5) is at least 2 and the second character of
Result(5) is x or X, go to step 17.
14. Let R be 8.
15. Let S be Result(5).
16. Go to step 22.
17. Let R be 16.
18. Let S be the substring of Result(5) consisting of all but the first
two characters.
19. Go to step 22.
20. Let R be 10.
21. Let S be Result(5).
22. If S contains any character that is not a radix-R digit, then let Z be
the substring of S consisting of all characters to the left of the
leftmost such character; otherwise, let Z be S.
23. If Z is empty, return NaN.
24. Compute the mathematical integer value that is represented by Z in
radix-R notation. (But if R is 10 and Z contains more than 20
significant digits, every digit after the 20th may be replaced by a 0
digit, at the option of the implementation; and if R is not 2, 4, 8,
10, 16, or 32, then Result(24) may be an implementation-dependent
approximation to the mathematical integer value that is represented
by Z in radix-R notation.)
25. Compute the number value for Result(24).
26. Return sign Result(25).
Note that parseInt may interpret only a leading portion of the string as
an integer value; it ignores any characters that cannot be interpreted as
part of the notation of an integer, and no indication is given that any
such characters were ignored.
