adding array elements	Can't Post

here's the deal, I have an array with a varying number of elements (all numbers 0.5, 1, 1.2, 2.4, .....)
How can I iterate through the array adding each element to achieve a single variable as the total?
Remember the array may not ever have the same number of elements.
thanks
paul

You can use the foreach in order to loop through an array with dynamically changing number of elements.
Another option is use of $#array expression which returns the last index in the @array.

Example:

Code

foreach $i (@array) { 
    $sum += $i; 
} 
 
or 
 
for ($i = 0; $i <= $#array; $i++) { 
    $sum += $array[$i]; 
}
