>I just asket my math engineer friend and he says 512 is true. VFP is wrong. You know Fortran written for engineering calculations. I trust Fortran when math is issue. BTW my math engineer said just me "Foolish excel goes left-to-right at this calculation". He says "If you write that calculation based on analytical you have to go up to down so the answer is 512".

Again. There is no wrong or write. Its all definition and knowledge. I myself simple mistrust anything except parenthesis if we talk about comps and comp languages.
