Bug #78354 [NEW]: Literal int64 min is treated as a float
From: dktapps at pmmp dot io
Operating system: Windows 10
PHP version: 7.3.7
Package: *General Issues
Bug Type: Bug
Bug description:Literal int64 min is treated as a float
Description:
------------
On 64-bit PHP, hardcoding the literal -9223372036854775808 or
-0x8000000000000000 produces a float instead of an int. This appears
to be some kind of parser bug, because introducing a subtraction into
the mix avoids the problem (see below).
Test script:
---------------
<?php
var_dump(-9223372036854775808);
var_dump(-9223372036854775807 - 1);
var_dump(-0x8000000000000000);
var_dump(-0x7fffffffffffffff - 1);
Expected result:
----------------
int(-9223372036854775808)
int(-9223372036854775808)
int(-9223372036854775808)
int(-9223372036854775808)
Actual result:
--------------
float(-9.2233720368548E+18)
int(-9223372036854775808)
float(-9.2233720368548E+18)
int(-9223372036854775808)
