String round(
  1. String str,
  2. int prec
)

Implementation

String round( String str, int prec ){
  String ret = "";
  for( int i = 0; i <= 8; i++ ){
    if( i != 0 ){
      ret += " ";
    }
    MPData a = MPData();
    mp.fset( a, mp.F( str ) );
    mp.fround( a, prec, i );
    String tmp = mp.fnum2str( a, prec );
    ret += tmp;
  }
  return ret;
}
