#2183 closed Bug (No Bug)

bitand not 64-bit,or 64-bit version not offered, srandom not 64-bit

Description

SRandom is not 64-bit.
bitand and similar functions are not 64-bit. consequently, when I try to create an integer timestamp to use as a seed, it always comes out as the same number.

OR bitand and their associated functions and srandom are just broken.

local $y=(@YEAR * 1000 * 60 * 60 * 24 * 31 * 12)
local $mo=((@MON-1) * 1000 * 60 * 60 * 24 * 31)
local $d=((@MDAY-1) * 1000 * 60 * 60 * 24)
local $h=(@HOUR * 1000 * 60 * 60)
local $mi=(@MIN * 1000 * 60)
local $s=(@SEC * 1000)
local $ms=@MSEC
local $timestamp=$y+$mo+$d+$h+$mi+$s+$ms
$timestamp=BitAND($timestamp, 2147483647)
msgbox(0,"timestamp",$timestamp)
SRandom($timestamp)
msgbox(0,"SRandom'd Random",Random(1,200,1))

please fix. thanks.

I also don't see any functions which convert a normal 64-bit integer into a 32-bit integer.

Did you try the flag parameter of Int()?

Also read the ticket guidelines again. 3.3.6.1 is NOT the latest version.

I had looked at Int() before, but had not noticed a flag parameter on it. thank you.

what's really bad about the documentation for Int() on that flag on conversion from 64-bit down to 32-bit is, I am left with a question: exactly what part of the integer gets taken? high or low word?

comment:5 Changed 8 years ago by anonymous

something that gives the user a choice of either a bit shift or a word selection would be nice in the case of Int(somenum,1). they may want only the high word,or they may only want the low word. or they may want something in the middle. the current bit routines are only 32-bit, which limits/breaks the ability to do proper conversions in some cases.

maybe I should be splitting this into 5 separate and somewhat similar-looking bug reports... but I chose to do it in 1 to save you and me headache.

you only solved PART of the problem. there is still a problem with the bit functions not handling 64-bit integers. I would not even mind if they had different names like bitand64(), bitor64(),bitnot64(),bitrotate64(),bitshift64(),bitxor64(). Bitrotate doesn't really need a "64" version, it simply needs the parameter "Q" for QWORD (QuadWORD) (a microsoft C++ data type).
