Hi all, I'm writing some coordinate transformations (more specifically the Joukoswky Transform, Wikipedia Joukowsky Transform), and I'm interested in performance, but of course precision. I'm trying to do the coordinate transformations in two ways: 1) Calculating the real and complex parts in separate, using double precision, as below:...

Given a integer number and its reresentation in some arbitrary number system. The purpose is to find the base of the number system. For example, number is 10 and representation is 000010, then the base should be 10. Another example: number 21 representation is 0010101 then base is 2. One more example is: number is 6 and representation os...

I have a file that contain list of numbers that looks like this: 10^-92 2 10^-14 10^-105 3 10^-20 To explain a bit further 10^-92 is essentially 1E-92 and 2 10^-14 is 2E^-14. Is there a compact way to convert the number in above file into Perl number? At the end I want to sort these numbers numerically. ...
