Maybe try to pass the value as a String instead of a
Number and eventualy remove the leading '0' in the String before casting it
as a Number

Subject: AW: [flexcoders] Re: Number("011") = 9 ????
Here it comes:
I have got Strings of the form "009", "010", "011",..., "999" which I expect
to be a decimal number, and so I was confused, that the output of
Number("011") is 9.
I didn't know that a 0 in front of literal is a specifier for octal
literals.
So parseInt("011",10) does exactly what I want to do. It interprets "011" as
the decimal 11.
My last question was only, whether there is a way to use the Number class to
produce this output, because I thought that it is not the most
object-oriented way to use the global function parseInt(...)...
Thanks for the replies
