type cast voodoo
Posted: Thu Sep 09, 2021 1:42 pm
Hi,
could somebody please check the following code (end of post) on an Ember system? I get different results on my 2 systems. The old Debian rack with Ember-1.9 produces the expected output:
digit=0
string=07727
digit=7727
string=7728
digit=7728
and so on
My new Ubuntu rack drives me crazy with
digit=0
string=07727
digit=4055
string=4056
digit=4056
and so on
If I use as starting string "07728" it gets even better:
digit=0
string=07728
Runtime error at line 17 of script 'casting_fun.ehtml'. Error is 'Type cast failed'
Looking at different bases there seems to be a connection with the octal representation. 7727 octal is 4055 decimal. But it's not what I need or expect, especially the type cast failure . . .
So, any hints to whether my machine is broken or my code or Ember are welcome.

$digit = (int)$string;
printf("digit=%d<br>\n", $digit);
$digit = $digit + 1;
$string = (text)$digit;
printf("string=%s<br>\n", $string);
$count = $count + 1;
