While I think the topic definitely deserves an article, I wonder whether "digital sum" is really the standard name for this operation? Casual googling seems to suggest that the digital sum of a number is more commonly taken to be the repeated digit sum, i.e. the decimal digital sum of 782 is computed by 7+8+2=17, 1+7=8 to be 8.

Yes, you're right. I'll try to correct this article. -- Alex Nisnevich (talk) 21:21, 26 July 2005 (UTC)[reply]
