Note: This question is all about the signedness of the second operand of bit shift operators << and >>. Not at all about the first operand.
So I\'m working on some MongoDB protocol stuff. All integers are signed little-endian. Using Ruby\'s standard Array#pack method, I can convert from an integer to the binary string I want just fine:
Suppose I have a function void foo(char *) which, internally, needs to treat its input as a block of NUL-terminated bytes (say, it\'s a hash function on strings). I could cast the argument to unsig
I am making an emulator for Z80 binaries but I cannot find out whether all the integer data types are signed or unsigned from the manual or from google. So are the n开发者_Go百科umbers from registers
Floating point values are inexact, which is why we should rarely use strict numerical equality in comparisons. For example, in Java this prints false (as seen on ideone.com):
