Detailed Description

A structure in which the result of sakura_ComputeStatisticsFloat and sakura_ComputeAccurateStatisticsFloat is stored.

You can also calculate following statistics from the members of this struct if count > 0:

• mean = sum / count
• rms = sqrt(square_sum / count)
• variance = abs(square_sum / count - mean * mean)
• stddev = sqrt(variance)
