Req #68456 [Asn->Wfx]: json_decode should be able to treat all numbers as strings

Edit report at https://bugs.php.net/bug.php?id=68456&edit=1 ID: 68456 Updated by: bukka@php.net Reported by: admin at bittylicious dot com Summary: json_decode should be able to treat all numbers as strings -Status: Assigned +Status: Wont fix Type: Feature/Change Request Package: JSON related Operating System: Linux Wheezy PHP Version: 5.4.35 Assigned To: bukka Block user comment: N Private report: N New Comment: The problem is that this number will never get saved with the full precision. You can influence the number of visible decimal places with setting ini precision as it is in http://3v4l.org/80iCh However as you can see the number is rounded because the internal float representation (C double type) cannot contain the whole number. So this is not JSON related. and any conversion to string can't fixed. The thing is that json_decode is using normal string conversion. So this can't be fixed in the JSON. I'd recommend you not to save the number to the the float at all but represent it as a string.

This is because some numbers can not be represented in a float properly. In reality, JSON is often used as a transport layer, and it's very useful to keep this accuracy. One example in practice where this has caused issues is when dealing with Dogecoin (a Bitcoin derivative). Dogecoin has eight decimal places, and because each Dogecoin is worth only a tiny fraction of a cent, they can often be represented as tens or hundreds of millions of Dogecoins. When you're dealing with finance, it's essential not to lose precision. The only workaround I have is to use a complicated preg_replace to add quotes to the original JSON string, which is nasty. Test script: --------------- <?php print_r(json_decode('{"test":1234567890.12345678}')); ?> Output: stdClass Object ( [test] => 1234567890.1235 ) ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=68456&edit=1
