Standard deviation in MeanStdDev doesn't return the result according to the documentation

Hello,

It seems than the MeanStdDev function doesn't calculate the standard deviation following the documentation. After doing a simple test I noticed that the result value is divided by the length of the imput vector and not "length - 1" as it was written on the documentation.

I used the following vector for my test: vec[10] = {0, 1, 2, 3, 4, 5, 6, 7, 8, 9}

I'm using IPP version 2019.0.5

Is it a known issue?
