Question

Simple calculation gives different result in java.

int a=5363/12*5;

out.println(a);// result is 2230 

But actually result should be 2234.5

How can this java result be rectified?

Answer 1

Two issues:

1. The expression 5363/12*5 gives an integer result (in particular, the division is integer).
2. The variable a is of type int (integer).

To fix:

double a=5363.0/12*5;
out.println(a);

Note that in general you can’t expect to get exact results when using floating-point arithmetic. The following is a very good read: What Every Computer Scientist Should Know About Floating-Point Arithmetic.
