ruby - Array of integers from file -


i trying grab large numbers file, store them array, , add them up.

nums = array.new x, total=0, 0 file = file.open("inputfile.txt", 'r') while !file.eof?   nums[x] = file.readline   x+=1 end  while x>0   x-=1   total += nums[x] end  puts total

when code executes, error saying:

string can't coerced fixnum (typeerror)

i checked make sure each array element has right data in it. think numbers considered strings when stored. if that's case, how change array integers can total them up?

just modify 

nums[x] = file.readline

to

nums[x] = file.readline.to_i

cheers!
