parseInt
Aug 31 2011 | 8:32 pm
Hi,
I don't get it. I got the following script:
test="05A";
post ("test is ");
post (test,"n");
post ( parseInt(test.slice(0,2)), "n");
test="08A";
post ("test is ");
post (test,"n");
post ( parseInt(test.slice(0,2)), "n");
This gives me the following output:
js: test is 05A
js: 5
js: test is 08A
js: 0
Why doesn't the second output give me 8?
Cheers

I find it confusing but the default radix depends on the input, see http://www.w3schools.com/jsref/jsref_parseint.asp definition and usage.
- Mar 30 2015 | 12:12 pmStarting the text representation of an integer with a spurious zero is, by longstanding convention, a flag to interpret the integer as an octal representation. Since the digits '8' and '9' aren't used in octal, the parser is likely to get confused.What happens if you drop the leading zero?
