I have two overloaded operators, one taking Object^ and the other taking bool. I expect the compiler to prefer the conversion from a double to Object^ (boxing) rather than to bool. as the former does not lose information and the latter does. Is this a valid expection (If so, then perhaps this is a bug).
Consider the following code:
String^ CreateOption( String^ name, Object^ value )
{
return name + "->" + value->ToString();
}
#if 1
String^ CreateOption( String^ name, bool value )
{
return value (name + "->True") : (name + "->False");
}
#endif
double d = 1.0;
CreateOption( "Test", d );
1>c:\sdclient\research\plot\MmaForm.h(484) : warning C4800: 'double' : forcing value to bool 'true' or 'false' (performance warning)
I want the compiler to pick the overload with Object^, and it does so if I were to #if 0 out the other overload.

Nevermind. Docs say:
A standard conversion will be chosen by the compiler over a conversion that requires boxing.
The workaround is to explicitly box:
double d = 1.0;
CreateOption( "Test", (Object^)d );
