Operating system: linux/debian
PHP version: 5.5.17
Package: JSON related
Bug Type: Bug
Bug description:json_decode rounding floats to 3 digits precision
Description:
------------
json_decode rounding floats to 3 digits precision. My precision setting
in php.ini shows 14.
Test script:
---------------
$tmp = json_decode('{"number":1000000.66599998}', true);
if (false !== strpos((string) $tmp['number'], '1000000.666')) {
echo PHP_EOL, 'WRONG', PHP_EOL;
}
else {
echo PHP_EOL, 'OK', PHP_EOL;
}
var_dump($tmp, $tmp['number']);
Expected result:
----------------
After decode the value of $tmp['number'] should be 1000000.66599998.
Actual result:
--------------
After decode the value of $tmp['number'] shows be 1000000.666 (it rounds
real value with 3 digits precision)
