Re: [Dev-C++] unspecified? Why?

[Per W. <pw...@ia...>]

It's the reverse. There are a number of mathematical operations available
on complex that doesn't make sense with int.

pow, cos, sin, sqrt, tan, polar, ...

sin and cos returns a result in the -1..1 range. An integer can only
store, -1,0,1 which obvisoulsy means you can only process the angles 0,
90, 180, 270.

A complex number is by mathematical definition a superset of a floating
point number, containing a real and an imaginary part (each a floating
point number) so obviously you can't use two integers.
