How to get actual calculation value from airthmatic operation

Question

I have this code:

float result = (85000/12)*5;
System.out.println(result );

the value of result is coming 35415.0 but the actual calculation result is 35416.66 .

I tried all data types but didn't get actual value. how should i get it.

Try using `float result = (85000/12.0)*5` – xabush Dec 12 '17 at 08:09 — xabush, Dec 12 '17 at 08:09

(85000 / 12) * 5; is evaluated as you see it: 85000 / 12 is evaluated in integer arithmetic - the remainder is discarded. The result of that is multiplied by 5.

To retain the float type of the compile time evaluable constant expression, use 85000f / 12 * 5.

I always promote the first coefficient, (i) for clarity, (ii) because something like 85000 / 12 * 5f will exhibit truncation effects.

You need to change the type to double too – Dogukan Zengin Dec 12 '17 at 08:10

`85000.0 / 12 * 5` wont compile as float but `85000f / 12 * 5` is the right answer – Dogukan Zengin Dec 12 '17 at 08:13
thanks Dogukan Zengin. u r right – im_mangesh Dec 12 '17 at 13:27
