Integer Division

[juliusbrehme]

Hello everyone,

I have the following code:

  Expression exp1{10};
  Expression exp2{3};
  Expression result{exp1/exp2};

The expected result of the Expression is 3, because of Integer Division, but I get 3.3333. If I do the following:

Expression result{10/3};

I get the expected 3.

I don't know if that is intended or not.

Thanks in advance.

  Expression exp1{10};
  Expression exp2{3};
  Expression result{exp1/exp2};  // result = 3.3333

This is expected behavior. A constant expression holds a double value and division between expressions is handled not following the integer division rule.

  Expression result{10/3};

Here, 10/3 = 3 is computed before it is passed to the constructor of Expression class. There is nothing much we can do about it. This is how C++ works.
