shouldn't this return 0821?

Code: Select all

> (integer? 0821)
true

Not really - at least, not in newLISP... You didn't specify a number base, and then you announced an octal number with the initial "0". But then you blew it with the "8", which is not a valid octal digit. Also, you didn't specify a default value in the event of a failed conversion, so you got the default default, which is 0.

Try:

Code: Select all

(int a 0 10)

I will sanitise the input before conversion

Code: Select all

(int (trim "0034234230" "0" ""))
=> 34234230

also consider speed:

Code: Select all

> (time (int "0821" 0 10) 1000000)
95.273
> (time (int (trim "0821" "0" "")) 1000000)
530.1
