hi i am creating some variables from same data, but somewhere is different
 P = abs(fft(d.zlato)/480)^2 
 hladane= sort(P,decreasing=T)[1:10]/480 
 for (j in 1:5){ for (i in 2:239){
  if (P[i]/480==hladane[2*j-1]){pozicia[j]=i-1}}}

> P[2]/334 
 [1] 0.0001279107 
 > hladane[1]
 [1] 0.0001279107
 > P[2]/334==hladane[1]
 [1] FALSE
> abs(P[2]/334 - hladane[1]) < 0.0000001
 [1] TRUE

It is possible to avoid it ?
I know in this exam i can use 2x if to eliminate this rouding, but i need to
fix it in general.
