I find it strange that there is no decimal number class in Boost for C++. C# has a special decimal type built-in. I mention this because I think there is a greater need for that kind of stuff than complex numbers. The ability to save monetary amounts with no internal repeating decimals.
Python has both complex numbers builtin and a Decimal numbers module.
I haven't used the Boost libraries at all, been out of the C++ ecosystem for a while now.
Complex numbers are super useful for physics stuff and also for optimisation. I just implemented it as a practice exercise, would be really surprised if there isn't a library for complex numbers already existing in Clojure.
One really cool feature in Clojure is the symbolic representation of rational numbers:
(/ 1 3)evaluates to
1/3rather than0.3333. This allows more precise calculations, as rounding only needs to be done at the end.Posted Using LeoFinance Beta
Oh wow. If you write 0.20, it will be a repeated decimal in Clojure, won't it? So instead you could handle 0.2 by writing (/ 1 5).
Yes exactly.
0.2would be of typedoubleand1/5is called "ratio" type in Clojure.Posted Using LeoFinance Beta
