If i do (i.e.) y= cos(x) where 0 < x < 2*pi and i'm testing the following:
   #if(y < 0)
      //block1...
   #else //block2...

the result when x= pi*3/2 is block1! And taking a look at its value, is
-0.00000 and is taken as negative number. By now i correct it simplyly
checking such y value:  #macro correct(num)(num<0?:num=0?0:num:num) #end

Can someone confirm if this is a bug? Thanks

(sorry, but my english is very bad)
