wp_send_json* functions do a weird float values conversion
I have a method that does simple math and returns a float value. I use this value as an argument for wp_send_json() function. Values are converted in a way that I don't understand.
$x = $calculator->getValue(); // Returns 3.02
$y = 3.02;
gettype($x); // Returns double
gettype($y); // Returns bouble
wp_send_json_success(%x); // prints {"success":false,"data":3.0199999999999996}
wp_send_json_success($y); // prints {"success":false,"data":3.02}
I don't' understand it at all. Both $x and $y values are exactly the same in terms of values and types. So why the outputs produced by wp_send_json_success are different?
Update:
Now I'm even more confused
$x === $y; // returns false
$x == $y; // returns false too!
How is it possible? When I do var_dump I can see that the values are the same.

It has nothing to do with wp_send_json(). In my code the 3.02 value returned by the $calculator->getValue() method is a result of a 10 - 6.98 equation. It returns 3.0199999999999996 but when I var_dump it then the result on the screen is rounded to 3.02. That's why $x == $y returns false.
