How can I keep the last decimal number in the actual value?

In this method, the expected number and the actual number are not equal to each other. In the expected value, it keeps the nearest one decimal while the actual value is not. So I use the Math. round but it only gives me the decimal is 0.

My question is how to make the actual value and the expected value are equal?

@Test
void testCalculateBMI(){
int
height1
= 12 * 5 + 5;
assertEquals( expected: 22.5, calculateBMI(height1, weight: 135.0));
int
height2
= 12 * 6 + 6;
assertEquals( expected: 20.8,calculateBMI(height2, weight: 180.0));

public static double calculateBMI(double height, double weight) {
return Math.round(703 *
weight / (height * height));
}
