Nettet2. aug. 2015 · If you have an exact log of a number z that is close to x, calculate w=x/z. w will be close to 1. And it is quick and easy to calculate the natural log of numbers close to 1. Less crude: a1 = (1+w)/2, and approximate ln (w) = (w-1)/a1. This looks like trapezoidal integration 1 to w of dt/t. Nettet9. feb. 2024 · Next. 9.3. Mathematical Functions and Operators.
