Rounded division 1

[scienzia]

Is there an operator that gives as a result a rounded division.

I mean that 100 / 6 must give 17

(using floats is 16.66666.... , using int gives 16)

Thanks in advance

No a special operator.
It's so simple:

(int)((double)x/(double)y + 0.5)

Look at

floor()
ceil()

Both in math.h

floor() is round down, ceil() is round up. A common math (to a nearest int) rounding is as in the snippet above.

Try it on something negative, say -2.7

I was wondering about that... shifts out by one.
