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 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 ...

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 ...

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 ...

Learning to calculate square roots quickly can make a huge difference in your maths exams. Whether you're doing algebra, geometry, or other topics, being fast and accurate with square roots gives you ...

Mastering quick square root calculations boosts maths exam performance. Speed and accuracy provide a significant advantage in algebra and geometry. Memorising key square roots and using mental math ...
