| Stefan Landsberg | Hi,
i want one Program write, that The Quadratwurzel a number accounts. ABER it should not 6 Nachkommastellen rounds, separate as long as go on To one on Stop clicking.
question: (How) can the curtail on 6 Nachkommastellen with sqrt() and pow() turn off.
If not goes, then must I me ever a procedure dreamup The that power. but Please no Fertiglösung post. then learn I nothing.
another question: is in XProfan 10 The length one floats terminable? |

| Jac de Lad | No, No, No! Typischer Anfängerfehler. circa with the Inputs To calculate must You it first of String one Float transfiguring (see "Val()") and to spending in the MultiEdit again in a String (see "Str$()").
Declare
declare in&,out&,btn&,Result$,end%,input$
Window create
windowstyle 575
windowtitle "Quadratwurzel"
window 20,20 - 600,400
usefont "MS Sans Serif",20,0,0,0,0
Window style
in&=create("Edit",%hWnd,"25",5,5,580,20)
btn&=create("button",%hWnd,"Berechnen",250,30,100,30)
out&=create("multiedit",%hWnd,"",5,65,580,-270)
whilenot end%
WaitInput
case %key=2 : break
if clicked(btn&)
input$=gettext$(in&)
Result$=Str $(sqrt(Val(input$)))
settext out&,""
settext out&,Result$
endif
endwhile
Kürzer would your Prog so:
Declare
declare in&,out&,btn&,end%
Window create
windowstyle 575
windowtitle "Quadratwurzel"
window 20,20 - 600,400
usefont "MS Sans Serif",20,0,0,0,0
Window style
in&=create("Edit",%hWnd,"25",5,5,580,20)
btn&=create("button",%hWnd,"Berechnen",250,30,100,30)
out&=create("multiedit",%hWnd,"",5,65,580,-270)
whilenot end%
WaitInput
if %key=2
break
elseif clicked(btn&)
settext out&,Str $(sqrt(Val(gettext$(in&))))
endif
endwhile
to that Topic Berechnung:
You can either each place particular to charge let or a number quadrieren and depending on whether tappt im dunkeln To big or To small is always a little bit raise or take away. moreover must You the numbers in Strings Save and each place particular multiplizieren.

| | Stefan Landsberg | Hi,
I take for spending the ergebnisses one simple editfeld, but since I in my Program Yes on The available number always The recalculated place dranhängen wants, is it in my opinion unpraktisch and probably too too slow always first whom actually Text with gettext from the editfeld auszulesen, a new digit dranzuhängen, and then again The number with settext in that editfeld To write. Gibts there a better method or irgendeine message (Gibts a Page/File in the The messages on german declared are) ? |
| | | | |
| | | wm_copyData could you here help. |
| | | | |
| | Stefan Landsberg | Hello, thanks first but there somewhere ne Documentation in the The messages verständlich (best german) declared are? I look with msdn not so correctly. through! |
| | | | |
| | | clear, XProfan.com Search and google are The aide in such hardship! |
| | | | |
| | Stefan Landsberg | after I jetz finally again little time for XProfan found Have (school claim ne whole crowd time. particularly latein ) place I time again a question:
Why we in the if request no worth on The variable firstpart$ transfer? I Have already attempts tappt im dunkeln as integer To declarieren. goes neither:
Declare
declare in&,out&,calcbtn&,stopbtn&,Result$,end%,input$
PROC-part
Proc sqrtlong
Algorithmus to that wander of/ one Quadratwurzel
Parameters number$, output&, stopbtn&
declare vorkomma$, div2%, firstsqrt%, firstpart$
number$=translate $(number$, "," , ".") Dezimalkomma through Dezimalpunkt supplant
vorkomma$=substr$(number$,1,".") Digits to the comma in vorkomma$ Save
div2%=Instr(".",st$(substr$(len(vorkomma$ / 2),1,"."))) Verify whether The amount the Digits to the comma straight or ungerade is.
if div2% = 0
firstpart$=mid$(vorkomma$,0,2) first 2 Digits from vorkomma$ go in firstpart$ stored
firstsqrt%=substr$(st$(sqrt(val(firstpart$))), 1 , ".") it becomes The sqrt from firstpart$ formed (remainder becomes omitted)
else
firstpart$=mid$(vorkomma$,0,1) first digit from vorkomma$ becomes in firstpart$ stored
firstsqrt%=substr$(st$(sqrt(val(firstpart$))), 1 , ".") it becomes The sqrt from firstpart$ formed (remainder becomes omitted)
endif
locate 4,1 only to that testing what firstpart$ enhält
print "firstpart:",firstpart$ only to that Test what firstpart$ enhält

| | Stefan Landsberg | soo, I Have jetz another bisschen weitergebastelt, and it functions too everything so How I it wants. but jetz Have I again my Completed: sendmessage. what must I make, so the content the variable firstsqrt% on the editfeld out$ gesendet becomes? CompileMarkSeparationDeclare
declare in&,out&,calcbtn&,stopbtn&,ergebnis$,ende%,eingabe$

vorkomma$=substr$(zahl$,1,".") Ziffern vor dem Komma in vorkomma$ speichern
div2$=substr$(len(vorkomma$)/2,2,".") Prüfen ob die Anzahl der Ziffern vor dem Komma gerade oder ungerade ist.
locate 3,1
print "div2:",div2$
if div2$ = 0
firstpart$=mid$(vorkomma$,1,2) erste 2 Ziffern aus vorkomma$ werden in firstpart$ gespeichert
firstsqrt%=val(substr$(str$(sqrt(val(firstpart$))), 1 , ".")) es wird die sqrt aus firstpart$ gebildet (rest wird weggelassen)
else
firstpart$=mid$(vorkomma$,1,1) erste Ziffer aus vorkomma$ wird in firstpart$ gespeichert

| | Stefan Landsberg | ok then mach ichs first so. but later would it from folgendem reason still effizienter another method To take or:

wm_copyData could you here help. |
