Why smears these demonstration ex?

 

funkheld
These nProc is a demonstration of XPSE.

 {$CLEQ}
Declare  b!,c!

End

nProc ArcSin2

    Parameters a!
    //Formel which under umgesetzt becomes: arctan(a!/Sqrt(-a!*a!+1.0))

have I well something overlooking, durchschaue I now not attempt.

what very GEHTS you really? like Fließkommaoperationen in Assembler write?

Yes..., the would like I.

Habs not from whom eyes verlogen, look once in a while drüber what lying could.

so ists rather:
CompileMarkSeparation
nProc ArcSin2

    Parameters a!
    //Formel welche unten umgesetzt wird: arctan(a!/Sqrt(-a!*a!+1.0))
    mov eax,addr(a!)
    finit
    fld qword ptr [eax]
    fmul qword ptr [eax]
    fsubr qword ptr __xeTF_00//__xeTF_00 Konstante für 0.0
    fadd qword ptr __xeTF_01//__xeTF_00 Konstante für 1.0
    fsqrt
    fdivr qword ptr [eax]
    fld1
    fpatan
    fstp qword ptr [eax]
    wait
    return a!

endproc


Funktionierts?

The umgesetzte Formel is:
arctan(a / Sqrt(0.0 - (a * a) + 1.0))

less a get one through "fchs" zustande.
Pi Gibts through "fldpi"

fountain nenn' so did i yet: [...]

even if one:

{$pushkeyword fchs,faddp,st1}

writes circa these Keywords as "bekannt" To deklarieren,
then bleats jwasm:

Objektcode: TEST.asm(166) : Error A2054: Invalid instruction o
perands

warning: Error in the Assembler.


can now but many causes having.

Jup thanks.

[15:11:11] warning: undeklariert : FADDP
[15:14:13] Naehe: ~14, 'FADDP ST1'

somehow go The as Variable abused of XPSE.

These runs now through without Error.
but i see well the Printen not XPSE.

it'll geprintet : Nan

Thank you.

the NaN hardship a number gives XProfan from vlt. with "ungültigen?" Fließkommawerten.
