Potenzieren with negativer Base

 

Julian

the goes yet not. Weder with FreeProfan, yet with XProfanX2.
CompileMarkSeparation

it follows NOT The expected spending -4, separate these Message.



@Roland: can you the in the next Update implementieren?

No. (-2)^2 is +4. with -2^2 or. -(2^2) expect I -4.

negatives numbers cannot potentiated go, there this even solely with Ganzzahlen functions would. with "-2^2" has the - as Negationszeichen precedence to the ^ and corresponds to means "(-2)^2", means negativer worth.

OK - only again to Klarstellung for my begrenztes mathematisches understanding.
"Negative numbers cannot potentiated werden" is: "Negative numbers cannot of XProfan potentiated werden", or?
my Taschenrechner can the namely... too with Floatzahlen.

RGH
but not, if The number with the is potentiated, no Ganzzahl is, about -2^2.5.
(OK, if your Taschenrechner with i-numbers clear comes, is the naturally something other. XProfan knows only whom real Zahlenraum.)

Floatwerte as Exponent can it neither. but here goes it Yes around the Base. and there ought to still too one negativer Floatwert no trouble his

there the Exponent of type Float is, go negatives Basen even impossible. (the depends too so together, that The Delphi-Formel, The x^y errechnet, from this reason with negativer Base a Laufzeitfehler produced.
naturally could I, if the Sonderfall ganzzahliger Exponent zutrifft, another Formel bemühen ...

now there only another Error Message if The Base negative UND the Exponent not ganzzahlig is.
