uncorrect result

hi guys,

I was debugging something in java and I got an unexpected result for some of the calculation, if I simplify I get this one line

Code:

---

System.out.println(15-(3.5*3.8))

---

which would print out
1.700000000000001

I don't really understand where that 0.000000000000001 comes from.

thanks.

The result is fine. Read these:

thanks. I didn't know that.

You're welcome. If you need precision, have a look at BigDecimal
