Hi,
I have two 2-D double arrays.I need to compare each value from these two arrays after rounding to 4 decimal places.(both are having same rows and columns).I have the code

C#

var equal = data1.Rank == data2.Rank &&
Enumerable.Range(0, data1.Rank).All(dimension => data1.GetLength(dimension) == ¬
data2.GetLength(dimension)) &&
data1.Cast<double>().SequenceEqual(data2.Cast<double>());

This shows wrong result..because it is not rounding the values.
I need to compare values after rounding to 4 decimals.Pls help

XML

var equal = data1.Rank == data2.Rank &&
            Enumerable.Range(0, data1.Rank).All(dimension => data1.GetLength(dimension) == data2.GetLength(dimension)) && data1.Cast<double>().Select(v => Math.Round(v, 4)).SequenceEqual(data2.Cast<double>().Select(v => Math.Round(v, 4)));
