Euclidean division; quotient and remainder 1 call

Mon, 31 Aug 2026 04:25:30 +0000

Euclidean division results for negative dividends are different from regular integer divide and MOD which are 2 operations.

These functions each return both quotient and remainder in BYREF variables.

The function for LONGs is assembly. For now the QUADs is BASIC; assembly will take more work.

This is also at https://www.yarker-dsyc.info/Programs/Mi...idDiv.html with a few more words.

To make a set tuncate functions are at https://www.yarker-dsyc.info/Programs/Mi...teDiv.html

Code:
''The remainder/modulo operation performed by Intel math coprocessors (FPREM

''and FPREM1 instructions) is not Euclidean, Intel's idiv assembly instruction

''is not Euclidean division. They are both IEEE Standard 754.

''In Euclidean division the remainder is never negative. For negative dividends

''the quotient is 1 different than expected.

''From Google- "An example use of Euclidean division with a negative dividend

''is finding a repeating time or calendar offset, such as calculating what hour

''of the day it was a certain number of hours ago.

Where is pbusers.org?

Tue, 04 Aug 2026 09:42:38 +0000

It's been hard to visit pbusers.org lately and now it's totally gone. Anyone knows why?

Is PBUsers.org broken?

Tue, 04 Aug 2026 09:40:02 +0000

Hello @all,
especially @George Bleck

Did you notice that since a few days PBUsers.org doesn't work any more? By trying many times again I might pass the blocking. This happens with Firefox as well with SRWare Iron (Chrome Engine).

This is what I usually see when trying to visit PBUsers.org:

Does PB progs run well in WINE?

Mon, 27 Jul 2026 13:58:56 +0000

I saw this video https://www.youtube.com/watch?v=1ffjb0Eq0po
which states that windows apps can run be run in linux WINE

Did anyone try this try running PB progs in Wine ? and what's your opinions on this WINE ?

FFTW - Attn Dan Soper

Tue, 19 May 2026 12:57:23 +0000

Dan, I saw your post on the pbusers.org site. I am not registered there.
I have played with FFTW in the past.
It was a long time ago though, so not sure if everything you need is here, but it might get you started.
I could never make sense of the licencing for FFTW so moved to the Intel IPP, now OneAPI lib.
It includes a lot of other useful functions, but it takes a while to get into it

Here are my Declares:

    HalfComplexIDFT = 1

    DHT = 2

    DCT1 = 3

    DCT2 = 5

    DCT3 = 4

    DCT4 = 6

    DST1 = 7

    DST2 = 9

    DST3 = 8

    DST4 = 10

Announcements for updates

Mon, 13 Apr 2026 14:16:56 +0000

There is an improved version of the experimental code converter for JKB (JKB_Convert.exe), please download the update package (update.zip) and unpack over your existing installation.

Sounds good!

Mon, 13 Apr 2026 00:54:44 +0000

From: What´s different

Quote:The syntax is (with some minor restrictions) compatible to PowerBASIC. These restrictions are:

The bit that caught my interest

Quote:- Variables must not be declared with "DIM" anymore! ... Dim is exclusively used for dimensioning arrays.

Big agreement and self-imposed in my code.

Quote:THREADED is not supported ATM.

Aww, when thread is needed it is needed. Since I seldom need it its not a big handicap for now.

Quote:- You may still declare multiple variables of the same data type in one single line. "LOCAL a, b, c AS LONG" is accepted. "LOCAL a$, b AS DWORD, c AS LONG" throws an error, because a$, b and c represent different data types.

Also self-imposed.

I'll download now. I need to get closer to the bottom of "job jar" to try it.

What is different

Sun, 12 Apr 2026 12:43:52 +0000

What´s different

The syntax is (with some minor restrictions) compatible to PowerBASIC. These restrictions are:

- Variables must not be declared with "DIM" anymore!
LOCAL, GLOBAL, STATIC, INSTANCE or COMMON is required (= #DIM ALL in PB)!. Dim is exclusively used for dimensioning arrays. THREADED is not supported ATM.

- You may still declare multiple variables of the same data type in one single line. "LOCAL a, b, c AS LONG" is accepted. "LOCAL a$, b AS DWORD, c AS LONG" throws an error, because a$, b and c represent different data types.

- You may assign an intial value, e.g. "LOCAL x AS LONG = -1"

- With variables you cannot have type specifiers anymore except for "$" (dynamic ANSI string) or "$$" (dynamic wide string)

- There are new data types: QWORD (unsigned 64 bit integer), SBYTE (signed 8 bit integer), XWORD (DWORD in 32 bit and QWORD in 64), XLONG (LONG in 32 bit and QUAD in 64)

- Assembler code:
! cmp byte [esi], 0 -> byte ptr (the key word "ptr" is mandatory, assembler error otherwise)
! ret must become, ! retn, (ret ends a stackframe)

!.if (eax == 0)
! ... "
!.endif (MASM Hi-level syntax is possible)

XAX = EAX in 32 bit and RAX in 64 bit

- Reserved words: there is a list of words, which are forbidden as variable or procedure names, eg. pos, count, enter, comment et. al

- String expressions: no logical string expressions, but automatic build$
e.g. if a$ < b$ and c$ < d$ then
...

must be if a$ < b$ then
if c$ < d$ then
...

but a$ + b$ + c$, is always compiled as BUILD$(a$, b$, c$), BUILD$ is valid syntax, but it is not necessary anymore

- Conditional compiling: code inside conditional compiling blocks (even if condition is not met) must be compilable
you cannot code anymore:
#IF 0
-> you must pepend an apostrophe to make it a comment
#ENDIF

#TRACE, #PROFILE and #CALLSTACK make use of the OutputDebugString Viewer, this is still experimental

- Syntax:
PARSE (no special treatment for default separator "," and quotes)

ISTRUE (parenthesis are required, it´s a function not an operator)
ISFALSE (parenthesis are required, it´s a function not an operator)

FORMAT$ (only one formatting mask allowed)
JOIN$ (without BINARY option and special quote handling)
PARSE$ (without BINARY option and special quote handling)

PRINT (requires sparator (, ; spc() tab()) between expressions)

What´s new:

#SEH - in case of a GPF, the offending line is shown in the IDE

TIMING [END] - return elapsed time in µs, syntax: TIMING [END] qword/quadvar
ISVALID() - returns -1, if pointer points to valid memory, 0 otherwise

SIN - y = SIN([deg/rad], x) default is deg, applies to all trigonometric functions

Run 32 bit code:
As a first step try to run 32 bit code. Please adapt your code according to the above restrictions. If there are many places to adapt, the Replace Dialog (Ctrl + R) is your friend. The first line must be "#COMPILER JKB [32]", "F9" compiles and executes. The IDE will complain about errors.

Run 64 bit code:
64 bit code definitely needs adaptions: all pointers and handles (which are pointers in fact) must become 64 bit data types (DWORD -> XWORD and LONG -> XLONG). The first line must be "#COMPILER JKB 64".

There is a (still experimental) code converter (Credits to Norbert Spoerl for supplying ideas and major parts of code) for adapting existing code to the new requirements. You may use the menu (last item in "File" menu: "Prepare Source for JKB" ) or the top toolbar (a new button, next to the "command prompt" button on the right side). This feature is applied to current file in the IDE. A copy (.original) is made before. Yet you may still have to adapt some things manually.

Please don´t post in this thread, feel free to ask questions in "Discussions" thread
