Implementation of Java division result with decimal and progressive method

http://blog.csdn.net/windone0109/article/details/5355379 into a method: that is, the omission of the bit as long as greater than 0 to go into a bit;
Rounding Method: That is, the omission of the bit less than five are to be shed, but the omission of the bit on the full five to go into a bit;
There is also a
To the end of the law: that is omitted in the position whether or not full five are to be shed;

1. Divide with decimals

For example:

int a = 8;
int b = 3;
int c = ((double) LA)/b;

System.out.println (c);

System Printed: 2.6666666666666665

2, the realization of the progressive method

Implemented with Math.ceil (), such as Math.ceil (2.1), the result is 3.0

For example:

int a = 8;
int b = 3;
int c = ((double) LA)/b;

int d = (int) math.ceil (c);

System.out.println (d);

System printed: 3
