Why not use Double or Float to represent currency?
...
Because floats and doubles cannot accurately represent the base 10 multiples that we use for money. This issue isn't just for Java, it's for any programming language that uses base 2 floating-point types.
In base 10, you can write 10.25 as 1025 * 10-2 (an integer times a power of 10...

What is the performance cost of having a virtual method in a C++ class?
...ing as virtual. If all functions are virtual everything can be replaced by base classes - public, protected, private - everything becomes fair game. By accident or intention subclasses could then change the behavior of functions that then cause problems when used in the base implementation.

Can a class member function template be virtual?

@ddriver: 1. If the compilers sees void f(concr_base& cb, virt_base& vb) { cb.f(); vb.f(); }, then it "knows" which function is invoked at the point cb.f() called, and does not know that for vb.f(). The latter has to be found out at runtime, by the runtime system. ...
