percentage

Im trying to find a interest rate in my program. I need it to accept values like 6.9%. How do I multiply a number by a percent. Thanks

If you have a float with a percentage (like 6.9) in it, and call the percentage variable something like fPercent, you can do it like this:

Code:

---

fSmallValue = fLargeValue * fPercent/100.0f

---

that works great, thanks.

If you want to try and preserve as much accuracy as possible:

Code:

---

fSmallValue = (fLargeValue * fPercent) / 100.0f;

---

If you want to preserve as much accuracy as possible, use doubles :rolleyes:
