Being interested in C++ performance programming there is one aspect I really have no clue about- and that is the implications of using floating point calculations vs doubles vs normal integer ...
When subdividing intervals for arithmetic coding, the worst case scenario is that the final interval will have size 2^(1-n), where n is the number of unique symbols you are encoding. This will reach ...
I have been reading up on arithmetic coding and, while I understand how it works, all the guides and instructions I've read start with something like: Set up your intervals based upon the ...
2¹⁶-1 & 2⁵ = 2⁵ (or? obviously ?) A developer asked me today what is bitwise 65535 & 32 i.e. 2¹⁶-1 & 2⁵ = ? I thought at first spontaneously 32 but it seemed to easy whereupon I thought ...
It is common to use idioms such as: x/60.0 to force a floating-point division when x is an integer in languages which do not have distinct operators for integer and decimal division. Is this an ...
