when ever put big or small number through system.out.println() (in java), decides convert 0.003897 3.897e-3 hard read when going through temporary-testing-debug-log-thing.

is there way keep 0.003897?

use decimalformat like: #.#######

decimalformat df = new decimalformat("#.00");  

either use:

system.out.println( string.format( "%.6f", 123.456789d )
