Adding array bytes

I have a situation where I am reading data from a serial port and storing it in an array.

The data is a GPS coordinate. The array will look something like this.

array(0) = 5
array(1) = 2
array(3) = 5
array(4) = 6
array(5) = 2
array(6) = 1

and so on.

I want to make 1 number (525621) so I have one variable that is 525621 ( a long?) It may not be necessary for the last digit accuracy so perhaps it will fit in a word.

How do I do it?

Regards - Paul

number = array(0)*100000
number = number + array(1)*10000
number = number + array(2)*1000
number = number + array(3)*100
number = number + array(4)*10
number = number + array(5)

Alternatively,

Mike.
