The type bool, boolean, can true or false his
can for variables with the both Values generiert go.

thereby has true The nummerische Repräsentation 1 and false The 0.

on the other hand go any nummerischen values mismatched 0 as true interprets.
slight useful with while number mismatched 0  To Verify.

The spending one logischen Wertes How z.B.
(i<r) | (i==r)
for any variables with print yields too The numerische Repräsentation and not true or. false.

sometimes would like one but very true.

the can of course self hinbekommen, but beautiful would a

- or ?

True becomes (almost everywhere) not directly gewertet. In some Languages is it too -1.
therefore ought to one True How everywhere simply to derive.

mismatched False is True (alike whom worth it repräsentiert).

almost everywhere - but Infinity-Profan???

true -1 z.B. in VB Skript, is too a sinnvolle thing, because binary
false 0... 000
true 1...111

In Infinity there Bools:

var a=true
print a

yields true

however:

print true-a

yields not false, because the Minusoperator whom Datentyp on numerisch anhebt.

print 10==20

yields however false

very How

print true==true

true yields.

but:

w = (i<r) | (i==r)
print w
print (i<r) | (i==r)
print i==i

gives z.B.:
1
1
true

look time:
var i,r,w = (i<r) || (i==r)
print w
print (i<r) || (i==r)
print i==i

false
false
true

there be I beautiful reingefallen, had still time my Java books take should.
but reference is law!

come with | and || as well as & and && but too always confusion.

small consolation, has otherwise yet none notice or itself getraut To monieren.

take I ex now a "Eselsbrücke"

Bits are small - apiece one characters | &
Logik is something large - means apiece two characters || && .

but one characters ! (negation) is logical, there becomes it then again unlogisch.

Übrigens one Another reason Why -1 for true too makes sense:
Invertiert one 0...000 (false) bitweise, gibt's 1...111 is (-1).
