One day while working on a task with another engineer, we needed to take the square root of a rather large number and both of us had momentarily misplaced our calculators. “Okay”, I said. “It'll just ...

Hackaday reader [nats.fr] wrote in with some code from a project that resizes a video stream on the fly using an FPGA. Doing this right means undoing whatever gamma correction has been applied to the ...

We present a novel idea to compute square roots over finite fields, without being given any quadratic nonresidue, and without assuming any unproven hypothesis. The algorithm is deterministic and the ...

We give new algorithms for the computation of square roots and reciprocals of power series in C║x║ If M(n) denotes the cost of multiplying polynomials of degree n, the square root to order n costs ...

A lot of times when simplifying square roots incorrectly students will say, "Oh, well I have an x squared. So that means if I took the square root of that then I that will be just x. And here's a 9, ...

A new DNA computer calculates square roots of perfect squares up to 900. Like quantum computers, DNA computers are an exciting frontier of post-silicon computing. Where previous examples were up to 4 ...
