Tim,
This is on the Fractint bug list:
Try cycling between float and integer math.
>>>>>
16/32 bits problem ? : With this in a PAR file:
squares { ; Floating Point !!
reset=2000 type=formula formulafile=thomas.frm formulaname=Squares
passes=t center-mag=-1.64e-006/2.205e-006/0.6666676 params=3/0 float=y
cyclerange=0/253 sound=beep/fm/quant colors=(a)default.map
}
squares2 { ; Floating Point !!
reset=2000 type=formula formulafile=thomas.frm formulaname=Squares
passes=t center-mag=0/0/0.001 params=3/0 float=y
cyclerange=0/253 sound=beep/fm/quant colors=(a)default.map
}
and that in THOMAS.FRM :
frm:Squares {
s2=sqrt(2)
ampl=1/0.02
ang=3.1415926535898/real(p1)
cs=cos(ang)
sn=sin(ang)
px=pixel
a=real(px)
b=imag(px)
z=0:
c=s2*(a*cs-b*sn)
d=s2*(a*sn+b*cs)
a=c
b=d
z=z+1
ampl*(abs(a)+abs(b))>1
}
Between my old 486 and my Celeron (out of windows) there is not at all
the same result !!Why ? (I have images if you want)
Limit problem: With the same formula,switch "Floating point" to off.
Edit the formula and change 1/0.02 by 50 In the first case,
maxiter is near 50 (I don't know exactly) and in the other one,only 15 !!
<<<<<<
From what I can determine, the conversion to the float parser formula gets
messed up. The value in vsp and LastInitOp are not correct when running with
floating point math.
