Size of long array

exactly so My example actually shows two problems with summing a huge number of small values (random numbers are between 0 and 1). The first, obvious is roundoff error and the second is the finite density of real values in the computer representation. In 4-bytes reals, above the magic value of 16777216, is it impossible to add a number less than one and get the result any different. Using higher precision accumulator helps with that. But, I must say, @ivanpribec’s trick with sum…
