34.5 => 34 round

[mrm40]

Hi,
in matlab there are functions that round integers,
im using visual studio 2010 c++,
functions in matlab are:

ceil(34.5) // result is 35;

floor(34.5) // result is 34;

is there any thing that does such thing in c++ ?

#include <cmath>

std::floor(number);
std::ceil(number);

i think you could do something like this

int round(double x) {
      x += .5;
      return x;
}

there is plenty of functions in <cmath>:
std::ceil() rounds towards +∞
std::floor() rounds towards −∞
std::trunc() rounds towards 0
