bool is a built-in basic type in C#. Any underlying representation would be an implementation detail. The C# 4.0 Language Specification states in section 4.1.8: The bool type represents boolean logical quantities. The possible values of type bool are true and false. No standard conversions exist between bool and other types. In particular, the bool … Read more
A fixed point number has a specific number of bits (or digits) reserved for the integer part (the part to the left of the decimal point) and a specific number of bits reserved for the fractional part (the part to the right of the decimal point). No matter how large or small your number is, … Read more
ast.literal_eval (located in ast.py) parses the tree with ast.parse first, then it evaluates the code with quite an ugly recursive function, interpreting the parse tree elements and replacing them with their literal equivalents. Unfortunately the code is not at all expandable, so to add Decimal to the code you need to copy all the code … Read more
However, variant c does not, probably because the new function takes only values of the same type which is not the case since Fooer != i32. No, it’s because there is no new function for Box<dyn Fooer>. In the documentation: impl<T> Box<T> pub fn new(x: T) -> Box<T> Most methods on Box<T> allow T: ?Sized, … Read more
The easiest way is probably to create an std::bitset representing the value, then stream that to cout. #include <bitset> … char a = -58; std::bitset<8> x(a); std::cout << x << ‘\n’; short c = -315; std::bitset<16> y(c); std::cout << y << ‘\n’;
The most recent example I can find is the UNISYS 2200 series, based on UNIVAC, with ones-complement arithmetic. The various models were produced between 1986 and 1997 but the OS was still in active development as late as 2015. They also had a C compiler, as seen here. It seems likely that they may still … Read more
