Convert int to double

int myInt = 255;
System.out.println("int value=" + myInt);

BigDecimal bdInt1 = new BigDecimal(Integer.toString(myInt));
BigDecimal bdInt2 = new BigDecimal(100);

bdInt1= bdInt1.divide(bdInt2);
double d = bdInt1.doubleValue();
System.out.println("double value=" + d);

Convert double to int

double myDouble = 2.55;
System.out.println("double value=" + myDouble);

BigDecimal bd1 = new BigDecimal(Double.toString(myDouble));
BigDecimal bd2 = new BigDecimal(100);

bd1= bd1.multiply(bd2);
int i = bd1.toBigInteger().intValue();
System.out.println("Int value=" + myDouble);
