halvnumber() c++ code

[firebird]

need c++ code for halvnumber() which recieves an int passed into it, divided by 2 which can be a double.

Can anyone help me?

[guruplus]

double halvnumber(int i)
{
return (i/2);
}

[ropez]

double halvnumber(int i) {
  return i / 2.0; // Must include ".0", or it won't work
}

[guruplus]

why it will not work?
is there any reason?

[z05DSL3A]

double halvnumber(int i)
{
return (i/2);
}

would do an integer division

[guruplus]

But visual c++ compiler return double without ".0", anyway, thanks for that information

[z05DSL3A]

That is because the result of the integer division is ‘cast’ to double to be returned.
What would be the result of ‘halvnumber(1)’?

[guruplus]

yeah, you are right;)
without ".0" it returns 0.000, with it, it returns 0.500
