Good afternoon, I'm a beginner in Java and I need to do the following calculation in the language
For example: (8/7) * 100 = 114%
(4/7) * 100 = 57.14%
(90/112) * 100 = 80.35%
But the way I'm developing it does not return the correct result.
double total = (90/112) * 100 ;
System.out.println(total);
and it returns me 0.0 in the console
How would I get the actual result back?
( 90/112 ) is a division of integers.
You can cast at least one of the operators to get the desired result:
double total = ((double) 90 / 112) * 100;
System.out.println(total); // 80.35714285714286
Other ways to cast:
double total = (90d / 112) * 100;
double total = (90.0 / 112) * 100;
There are two ways to resolve this:
double total = (90/112d) * 100 ;
System.out.println(total);
Or:
double total = (90./112.) * 100 ;
System.out.println(total);
