# Thread: Why raiseSalary equation can't work? empolyee.java

1. ## Why raiseSalary equation can't work? empolyee.java

why in raiseSalary(): salary *= (100 + percent) / 100 won't work?

```
// why salary *= (100+percent)/100 wont work?
}public void raiseSalary(int percent){
salary = salary*(100+percent)/100;```

2. ## Re: Why raiseSalary equation can't work? empolyee.java

Simplify the equation in the method to see if you can answer your own question. When you've obtained the simplified equation, don't forget to apply the rules of 'integer math.'

I am able to do it by adding a (double). thanks for the help.

```     }public void raiseSalary(int percent){
salary *= (double)(100+percent)/100;```
