Regardless of the bit-width of the number system, more importantly, the maximum relative errors of the proposed approximations are bounded to 6.25% and 3.13% for square and square-root functions, respectively.In-Cheol ParkTae-Hwan Kim2009 IEEE International Confernece on Computer Design (ICCD ...
Square-root algorithms for the smoothing problem are presented and as in the discrete case, an array method for handling continuous squareroots is developed. This method also yields very naturally the usual normalizations of stochastic calculus, suggesting extensions to more general stochastic equations...

The square root of the variance is also known as standard deviation. SQL Server Analysis Services does not provide the standard deviation but you can easily calculate it. For each regressor, three rows are output. They contain the coefficient, score gain, and reg...
Question. Show that if a matrix is orthogonal and triangular, then it is diagonal. What are its diagonal elements? Proof. Take A=(a_1, \dots, a_n) an upper(lower) triangular and orthogonal matrix. It is the same for lower triangular. Noticing that A^{-1} is an upper(lower) triang...
