Convert number type in calculation equation

[laichunguang1]

Hi guys.
Is there a easy way to convert number type in calculation equation?

For example:
out 100*(1/2)
it return 0

But in real math calculation, it for sure will get a result of 50.
It is because (1/2) step gets a result of int 0 instead of 0.5 imo.

So I wonder what function I can add before (1/2) to make it get 0.5?
And make "out 100*(1/2)" return 50?

Thank u for the help in advance.

Make some of the numbers double.

out 100*(1/2.0)

Thank u, it works!
And then after I convert it to double, how I can convert it to int again?
