okay! ic........ understand what you are explaining.......... o it explains why the need for the
[quote](int)(v+0.5) // if v>0  // 2.3 become 2  2.5,2.7 become 3 (variable >=2.5 become 3, <2.5 become 2)
(int)(v-0.5) // if v<0
will give you integer value.[/quote]

I did a little trial and error

use i replace i with j for typing here

l_n[j] = ""+j; // This is the code i was thinking of  ;D

because i or j is already an integer

but l_n[j] is a string, so i added the  "" and add a plus j, to make the variable j into a string

now it works  ;D Thanks!
