help.. Problems in using awk

I do have a file (named as templist) which looks like this one:
00450000.000000 00402300.000000 00040000.000000 00020000.000000 00020000.000000 00020000.000000 00020000.000000

and I want to make a script that adds this using AWK or FOR.
I tried using awk using the command
Quote:
/awk '{sum=sum+$1;printf("sum: %.0f\n",sum)}' < templist
but it just returns the value of the first variable 450000.

please help me to modify my command.
thanks

Code:
$ echo 00450000.000000 00402300.000000 00040000.000000 00020000.000000 00020000.000000 00020000.000000 00020000.000000 \
| awk -v RS=" " '{sum=sum+$1;printf("sum: %.0f\n",sum)}'
sum: 450000
sum: 852300
sum: 892300
sum: 912300
sum: 932300
sum: 952300
sum: 972300

thanks for this

Quote:
cat templist | awk -v RS=" " '{sum=sum+$1;printf("sum: %.0f\n",sum)}' > total
this outputs:
Quote:
$ cat total
sum: 450000
sum: 852300
sum: 892300
sum: 912300
sum: 932300
sum: 952300
sum: 972300
is it possible to output only the final result in the file "sum: 972300"

remove the cat. Use the END {} block
Code:
awk -v RS=" " '{sum=sum+$1} END { .... }'  templist > total

i tried using this one:
Quote:
awk -v RS=" " '{sum=sum+$1} END printf("sum: %.0f\n",sum)}' templist > total
but its giving me an error
Quote:
syntax error The source line is 1.
The error context is
{sum=sum+$1} END >>> printf <<< ("sum: %.0f\n",sum)}
awk: There is an extra } character.
awk: Quitting
The source line is 1.
