晚上好, 我的代碼不會四捨五入,我不知道爲什麼!請幫忙! import java.util.*;
import java.math.*;
public class Arithmetic {
public static void main(String[] args) {
Scanner scan = new Scanner(System.in);
int
下面的測試失敗: @Test
public void testRound() throws Exception {
double v = 0.015d;
DecimalFormat format = new DecimalFormat("#.##", new DecimalFormatSymbols(Locale.US));
format.setRoundingMo
在Fortran中,我希望能夠將大型雙精度浮點數舍入爲最接近的整數。我嘗試了這個原則, PROGRAM rounding
IMPLICIT NONE
INTEGER, PARAMETER :: DP = 8
REAL(KIND=DP) :: value
value = 12345678987.123456
print *, CEILING(value)
END PROGRAM R
