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 ...
I am aware that floating point arithmetic has precision problems. I usually overcome them by switching to a fixed decimal representation of the number, or simply by neglecting the error. However, I ...
I knew double or float value can be not only normal value(-1.3, 0, 1.0, 2.3) but also NAN and INFINITY in Objective-C. Is there other special values except for NAN and INFINITY for double/float value ...
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 ...
I have made a python code to smoothen a given signal using the Weierstrass transform, which is basically the convolution of a normalised gaussian with a signal. The code is as follows: #Importing ...
Is there an alternative to bits as the smallest unit of data? Something that won't be only 0 or 1, but actually hold many possible states inbetween? Wouldn't it be more natural to store floats like ...
Conversion of a number from Single precision floating point representation to a Half precision floating point [closed]
I have a code where I have to work on Half precision floating point representation numbers. To achieve that I have created my own C++ class fp16 with all operators(arithmetic logical, relational) ...
I was watching http://www.joelonsoftware.com/items/2011/06/27.html and laughed at Jon Skeet joke about 0.3 not being 0.3. I personally never had problems with floats/decimals/doubles but then I ...
