friend

Compares two JSON values for equality according to the following rules:

- Two JSON values are equal if (1) they are from the same type and (2) their stored values are the same.
- Integer and floating-point numbers are automatically converted before comparison. Floating-point numbers are compared indirectly: two floating-point numbers `f1` and `f2` are considered equal if neither `f1 > f2` nor `f2 > f1` holds.
- Two JSON null values are equal.

Parameters

  [in] | lhs | first JSON value to consider
  [in] | rhs | second JSON value to consider

Returns
  whether the values lhs and rhs are equal

Complexity
  Linear.

Example
  The example demonstrates comparing several JSON types.
  #include <json.hpp>
  using namespace nlohmann;
  int main()
  {
  // create several JSON values
  json array_1 = {1, 2, 3};
  json array_2 = {1, 2, 4};
  json object_1 = {{"A", "a"}, {"B", "b"}};
  json object_2 = {{"B", "b"}, {"A", "a"}};
  json number_1 = 17;
  json number_2 = 17.000000000000001L;
  json string_1 = "foo";
  json string_2 = "bar";
  // output values and comparisons
  std::cout << std::boolalpha;
  std::cout << array_1 << " == " << array_2 << " " << (array_1 == array_2) << '\n';
  std::cout << object_1 << " == " << object_2 << " " << (object_1 == object_2) << '\n';
  std::cout << number_1 << " == " << number_2 << " " << (number_1 == number_2) << '\n';
  std::cout << string_1 << " == " << string_2 << " " << (string_1 == string_2) << '\n';
  }

  Output (play with this example online):

      [1,2,3] == [1,2,4] false
      {"A":"a","B":"b"} == {"A":"a","B":"b"} true
      17 == 17 true
      "foo" == "bar" false

  The example code above can be translated with

      g++ -std=c++11 -Isrc doc/examples/operator__equal.cpp -o operator__equal
