How to work out number of steps?

Ok, I've been playing with this for a while, but the solution has evaded me:(

Basically, I have a 'count' figure. Now, with this figure, I want to work out how many steps I would need to run.

For example;

15023 entries

Each step runs 1000 entries at a time...

I then need to work out how many steps of 1000 at a time I would need to run. i.e

15,023 / 1000 = 15.023. I then need to round this UP to 16, so that all the stages are completed.

Anyone got any ideas? Unsure

TIA

Hi,

my $total = 15023;
my $increment = 1000;
my $steps = int($total / $increment) + 1;

Cheers,

Alex

Aaah.. forgot about the int() function. I was trying to be all clever and use sprintf() Frown

Hi Alex,

slight correction (for the case when $total % $increment equals 0):

Code:
my $total = 15023;  
my $increment = 1000;  
my $steps = int($total / $increment); 
$steps++ if $total % $increment;

Thanks Ivan. I don't think that fix needs to be applied to my script though, as all its going to be doing is something like;

Code:
    my $table = $DB->table('Links');   
    my $count = $table->count( GT::SQL::Condition->new( 'type','NOT LIKE', 'Pay' ) ); 


    my $number_of_steps = int($count / 1000) + 1;  

     for (my $i = 1; $i <= $number_of_steps; $i++) { 
        `recip_check.cgi --Destination=$Destination --ID=$i`; 
     }

... which in effect, will result in the code running something like this (in order);

`recip_check.cgi --Destination=/path/to/admin/folder --ID=1`;
`recip_check.cgi --Destination=/path/to/admin/folder --ID=2`;
`recip_check.cgi --Destination=/path/to/admin/folder --ID=3`;
`recip_check.cgi --Destination=/path/to/admin/folder --ID=4`;
`recip_check.cgi --Destination=/path/to/admin/folder --ID=5`;

If there is an extra step, that shouldn't matter.. as all it will do is skip that stage in recip_check.cgi.

Thanks guys Smile
