Slide Ruler – L.R. Ingersoll Physics Museum – UW–Madison
WEBA slide rule is a mechanical analog computer that can be used to do many types of calculations, including multiplying and dividing. The first slide rule using multiple scales was designed by William Oughtred (1575 –1660). What to do. Move the middle of the slide rule so that the first number 2 on line B lines up with the first number 1 on line A.
What algorithm is used by computers to calculate logarithms?
WEBI would like to know how logarithms are calculated by computers. The GNU C library, for example, uses a call to the fyl2x() assembler instruction, which means that logarithms are calculated directly from the hardware.
Slide Rule - Mathematical Mysteries
WEBA slide rule, also known as a slide ruler or a slipstick, is an extremely complex ruler that functions as an analog computer. By sliding various components of the ruler to align with one another, a slide rule can compute products, roots, logarithms, and the result of trigonometric functions.
