How are logarithms calculated

Web24 de mai. de 2012 · In the case of the natural logarithm, there is an easy way to reduce the range. Real numbers are almost universally represented in terms of a mantissa and an exponent: x = m *2 p, where p is an integer and m is between 1 and 2. Thus log ( x) = log ( m )+ p *log (2). The latter term, p *log (2), is just a multiplication by a known constant. Web14 de fev. de 2016 · Generally, power series are efficient for natural logarithms of numbers near 1. You can do things to get your number near 1, such as multiplying by a power of ten or taking the square root, then adjusting the logarithm you get. Meanwhile, memorize the number 0.4343. That is the approximate logarithm of e.
