Operators

Operators knows Profan first since the Version 6. before get mathematical and Verknüpfungs-Operationen over functions Done. The functions existieren from Kompatibilitätsgründen furthermore, can but for zukünfige versions of XProfan not guaranteeing go.

there's following Operators:

Zuweisung:

Var = expression	Wertzuweisung

with the Wertzuweisung any Variablentypen possible. The expression ought to of equal type his as Variable. some values go automatically konvertiert (Int <--> LongInt, Int+LongInt -> Float). for (String <--> Int) ought to one always Konvertierungsfunktionen using ( @LINKF:[Int], @LINKF:[Str]$ ).

String:

A$ + B$	Strings verknüpfen; old: @Add$(A$,B$)
A$ = B$	comparison: Gleichheit; old: @Equ$(A$,B$)
A$ <> B$	comparison: Ungleichheit; old: @NEq$(A$,B$)

The Datentyp is here always of type String.

Mathematisch:

A% + B%	Addition; old: @Add(A%,B%)
A% - B%	Subtraktion; old: @Sub(A%,B%)
A% * B%	Multiplikation; old: @Mul(A%,B%)
A% / B%	Division; old: @Div(A%,B%)
A% B%	ganzzahlige Division: 5 2 = 2 (remainder falls lane); old: @Div&(A%,B%)
A% MOD B%	Modulo/Teilungsrest: 5 mod 2 = 1 (the remainder the Division); old: @Mod(A%,B%)
A% ^ B%	Potenz; old: @Pow(A%,B%)

The Datentyp Integer (%) standing here stellvertretend for: % (Integer), & (LongInt), ! (Float).

Relational:

A% < B%	comparison: small as (less than); old: @LT(A%,B%)
A$ < B$	comparison: small as (less than); old: @LT$(A$,B$)
A% <= B%	comparison: small or same (less or equal); (there were not as function)
A$ <= B$	comparison: small or same (less or equal); (there were not as function)
A% > B%	comparison: greater as (greater than); old: @GT(A%,B%)
A$ > B$	comparison: greater as (greater than); old: @GT$(A$,B$)
A% >= B%	comparison: greater or same (greater or equal); (there were not as function)
A$ >= B$	comparison: greater or same (greater or equal); (there were not as function)
A% = B%	comparison: Gleichheit; old: @Equ(A%,B%)
A% <> B%	comparison: Ungleichheit; old: @NEq(A%,B%)

The Datentyp Integer (%) standing here stellvertretend for: % (Integer), & (LongInt), ! (Float).

Logisch:

A% AND B%	logisches UND
A% OR B%	logisches ODER
NOT(A%)	logisches NOT (existing <b>nur</b> as function)

The Datentyp Integer (%) standing here stellvertretend for: % (Integer), & (LongInt).

Binär:

A% & B%	binäres UND
A% \| B%	binäres ODER
A% << B%	Bits to left schieben (in Delphi: SHL)
A% >> B%	Bits to right schieben (in Delphi: SHR)

The Datentyp Integer (%) standing here stellvertretend for: % (Integer), & (LongInt).

If the - too Parameter part (How about with LINKP:[WINDOW] and the many <a href="https://XProfan.com/index.mx?online-Documentation-rubriken/rub8">Grafik-Befehlen</a>), is it necessary Subtraktionen einzuklammern, about:
Window a%,(b% - 5) - (c% - 6),500

Anderenfalls can the Parser confusion get and there's Fehlermeldungen.

The Operators are following Hierarchiestufen eingeteilt:

1.	^
2.	MOD	AND	*	/	&	>>	<<
3.	OR	+	-	\|
4.	=	>	<
5.	<>	>=	<=

Info: The Hierarchie corresponds to vaguely the under PASCAL and weicht from the BASIC-Hierarchie ex. The Vergleichsoperatoren (level 4 + 5) are BASIC higher classed.

from BASIC:
If A% > 6 AND A% <= 20 THEN
<...>
End If

becomes in XProfan:
If (A% > 6) AND (A% <= 20)
<...>
EndIf

In PASCAL would one write:
If (A > 6) AND (A <= 20) THEN BEGIN
<...>;
End;

Klammerung is How normally allows,
about:
C% = 5 * (A% + B%)
Result! = 248 * d% / (e% + f%)

clinging can discretionary, d.h. until Stack-Überlauf, nested go.

Wichtig: respect tappt im dunkeln on The Klammersetzung. Version 7.5 pushing on Error, The Version 6.5 yet overlooking has! The Error Message "Zu little Parameter" in a row with verschachtelten functions/clinging deutet often on a Error in the Klammersetzung there!

Achtung: logical means, that the Result true (1) or wrong (0) is, with binären functions go The values bitweise verknüpft:

logical: 2 OR 4 yields 1, because at least of/ one the values <> 0 (= true) is

binary: @OR(2,4) or. 2 | 4 yields 6: %0010 OR %0100 = %0110

for speedy Berechnungen with Integer-Values, z.B. in creep, etc., there in XProfan additional some command, The faster and übersichtlicher are:

LINKP:[INC] V%	increased V% circa 1
LINKP:[DEC] V%	erniedrigt V% circa 1
LINKP:[ADD] V%,n	increased V% circa n
LINKP:[SUB] V%,n	erniedrigt V% circa n

(Hierbei standing V% for a arbitrary Integer- or Longint-Variable and n for a beliebigen expression.)

for the join of Strings (Zeichenketten) becomes the "+" akin:
Text$ = "Du are " + Str$(old%) + " years old."

of course functions in some versions too:
Text$ = "Du are ";Str$(old%);" years old."

however is only the Pluszeichen as Verknüpfungs-Operator definiert. It can therefore To fehlerhaften Programs lead, if not elaborate worked becomes.

Hinweis: The automatic Typumwandlung functions with einfachen variables. with functions, The a numerischen worth give back, won't always automatically transformed, therefore is here always The function @LINKF:[Str]$ To use! VOR and After whom Operators must one space stand. there some Operatorzeichen too in another Context using go, can Compiler and Interpreter otherwise fehlerhaften code produce.

Programmieren, das spannendste Detektivspiel der Welt.
