Previous Comments: ------------------------------------------------------------------------ [2002-07-07 13:31:19] derick@php.net This works fine for me on Linux with the latest development CVS version of PHP (On Linux) provided that you use printf ("LONG_MIN -1 = %f", LONG_MIN - 1); instead, because the value of LONG_MIN - 1 does not fit in a field with %ld. Can you try this with the latest CVS version, and report back? Derick ------------------------------------------------------------------------ [2001-12-20 13:45:09] markmont@umich.edu This problem causes all tests in ext/standard/tests/math to fail: <?php define('LONG_MAX', is_int(5000000000)? 9223372036854775807 : 0x7FFFFFFF); define('LONG_MIN', -LONG_MAX - 1); printf("%d,%d,%d,%d\n",is_int(LONG_MIN ),is_int(LONG_MAX ), is_int(LONG_MIN-1),is_int(LONG_MAX+1)); printf( "LONG_MIN = %ld, LONG_MIN - 1 = %ld\n", LONG_MIN, LONG_MIN - 1 ); printf( "LONG_MAX = %ld, LONG_MAX + 1 = %ld\n", LONG_MAX, LONG_MAX + 1 ); ?> This script gives the following results on my system: 1,1,1,1 LONG_MIN = -9223372036854775808, LONG_MIN - 1 = 9223372036854775807 LONG_MAX = 9223372036854775807, LONG_MAX + 1 = -9223372036854775808 Here's my setup: PHP 4.1.0 compiled as a 64-bit stand-alone interpreter (CGI).

Any thoughts as to what the problem could be? If I can be of help in fixing it, just let me know.
