Conversion from double to int by default

[Ivo Hanak <hanak@xxxxxxx>]

Hello,

 I am puzzled by the fact that g++ (4.4.1, 64-bit Gentoo) allows me to 
compile following line without any error:

 int value = 2.5;

 Also, the following program is compiled without any error or warning 
using 'g++ main.cpp':

#include <stdlib.h>
#include <iostream>

int main() {
  int value = abs(2.4);
  value = 2.5;
  std::cout << value << std::endl;
  return 0;
}

 I tried to search the web but I still do not have any clue why it 
converts from double to int by default. This seems pretty dangerous to 
me. Am I missing something?

 Thank you.

 IH.
