doubles and ints
Author
i have some compile errors of the type:
273 pong.cpp
warning: `double'' used for argument 2 of `SetPixelV(HDC__ *, int, int, long unsigned int)''
yes im putting a double in there and it should be an int, things compile and work tho.
should i do something aobut this, converting the double to int, (in that case how?) or is it alright to leave it as it is?(any performance loss or other evil stuff?)
thx
YOu might wanna do a static_cast<int>(your variable) to make it more obvious whats going on.. that will also remove the warning
yes, as AP said it''s only a warning. You can lower your warning level or always cast (static_cast) your types to the expected type

A warning is well.. a warning
Your compiler tells you that there is something which is possible to do but could become an error if you''re not aware of it.
If you cast it you tell the compiler that you know what you''re doing and he shuts up

Unless there is something fishy with your variables, just do:
double your_double = 1.3;
SetPixelV(hd, (int)your_double, what, ever);
