How do I round up currency values in Java

BigDecimal result = new BigDecimal("50.5399999").setScale(2, BigDecimal.ROUND_HALF_UP);

static long round(double a)

double d = 50.539999; // or however many 9's, it doesn't matter
int dollars = (int)d;
double frac = d - dollars;
int cents = (int)((frac * 100) + 0.5);

long money = 5054;

long cents = money % 100;
long dollars = money / 100; // this works due to integer/long truncation

System.out.printf("$%d.%02.d", dollars, cents);

double value = .539999;
int result = (int) (value*100);
if(((value*100)%result)>.5)
    result++;

num = .53999999;
int_num = (int)(num * 100); // cast to integer, however you do it in Java
compare_num = (int_num + 0.5) / 100;

dollars_and_cents = round(100*a)/100
cents = (dollars_and_cents-(int)dollars_and_cents)*100

double d = 50.539999;
long cents = (long)(d * 100 + 0.5);
double rounded = cents/100;
