numbers - Fixed decimal places double and power of ten format in java -

-

i'm writing code in java supposed manipulate data text file. in text file coordinates saved. layout of numbers always: 5.000000000000000+0 data read, manipulated , printed file. printing part not yet working, number of decimal places varies , haven't succeeded append power of ten in shown way. decimal numbers tried:

formatter.setminimumfractiondigits(15);

and 

formatter.setmaximumfractiondigits(15);

but still displays more digits sometimes. how can achieve shown format double numbers or @ least right amount of decimal digits?

use string.format:

    double x = 1.1231523235;     system.out.print(string.format("%.5f", x));

that print

    1,12346

and if want dot delimiter use

    system.out.print(string.format(locale.english,"%.5f", x));

mysql - FireDac error 314 - but DLLs are in program directory -

i getting when trying access mysql database : [firedac][phys][mysql]-314. cannot load vendor library [libmysql.dll or libmysqlld.dll] this did not happen (unchanged) code, however, have upgraded windows 10 , had reinstall delphi xe8, system configuration matter. in order try solve problem, copied both of files c:\windows\sysytem32. when did not seem work, copied them \win32\debug, generated .exe resides. i imagine doing rather stupid, can't see what. the proper solution place driver file (eg., libmysql.dll ) in application's folder, or place installation location in fddrivers.ini file: [mysql] vendor=<folder>\libmysql.dll (recent versions of documentation seem use vendorlib instead of vendor in ini file.) see rad studio documentation topics configuring drivers (firedac) , connect mysql server (firedac) more information.
