On: Streaming: a skill gap?

[mc13]

Exactly, i deal with a few of data processing programs, wish my more experienced colleagues told me about these algorithms before, but doesn't this algorithm only compute an approximation and not the exact value ?

[anonymoushn → mc13]

To about the extent that a 64-bit float can ever be said to contain an exact value, this algorithm will compute the exact value. There's no sampling.
