something looks wrong in this ikeda function

this should produce same of ikeda(1)

a          = 0.4;
b          = 6.0;
c          = 0.9;
x0         = 0.68587;
y0         = 0.65876;
TH=a-b/(1+x0^2+y0^2);
1+c*(x0+y0*j)*(cos(TH)+j*sin(TH))

ans =  0.65523 - 0.78338i

However on cygwin 64

> ikeda(1)
ans =

   1.21651   0.41790

on cygwin 32 bit

 ikeda(1)
ans =

   1.06022  -0.13853


and the expected value is

   0.28572    0.6434

I am a bit puzzled
