  • What is associativity of operators and why is it important?
    The Associative property in mathematics Order of Operations in programming languages Associativity in CPU caches The Associative property in mathematics is a property of operators such as addition (+) This property allows you to rearrange parentheses without changing the value of a statement, i e : (a + b) + c = a + (b + c)
  • c - Logic Proof of Associative Property for XOR - Stack Overflow
    The associative property says that (a^b)^c = a^(b^c) Since XOR is bitwise (the bits in the numbers are treated in parallel), we merely need to consider XOR for a single bit Then the proof can be done by examining all possibilities:
  • c++ - Should I use boost::property_map? - Stack Overflow
    In a nutshell, create a map m and an associative property map pm using m and you won't generate a redundancy More information follows boost::associative_property_map does not create a new map It only references another map and makes it accessible through the boost property_map API (get put) See the documented example here
  • Is floating-point addition and multiplication associative?
    Another grey area concerns the interpretation of parentheses Due to roundoff errors, the associative laws of algebra do not necessarily hold for floating-point numbers For example, the expression (x+y)+z has a totally different answer than x+(y+z) when x = 1e30, y = -1e30 and z = 1 (it is 1 in the former case, 0 in the latter)
  • Do the binary boolean operators have associativity?
    is an associative operation by nature Associative Property Within an expression containing two or more occurrences in a row of the same associative operator, the order in which the operations are performed does not matter as long as the sequence of the operands is not changed
  • python - Associative Matrices? - Stack Overflow
    The obvious way to express this is with an associative array of associative arrays, but this is both awkward and inefficient, and it doesn't enforce the non-jaggedness property Do any popular programming languages provide an associative matrix either built into the language or as part of their standard libraries?
  • Are floating point operations in C associative? - Stack Overflow
    Addition mathematically holds the associative property: (a + b) + c = a + (b + c) In the general case, this property does not hold for floating-point numbers because they represent values in a finite precision Is a compiler allowed to make the above substitution when generating machine code from a C program as part of an optimization?
  • c++ - What is a property map in BOOST? - Stack Overflow
    Towards your edit: make_iterator_property_map builds an iterator_property_map The first argument provides an iterator for a basis of offset calculations The second argument is again a property_map to do the offset calculation
