I have a type defined in the core library like..

Since D is superb, i like to know how you do it in D.
If you got a better idea in C++, i would like to hear that too!
You know there are float literal too, in C++/D, like: 5.5f
I don't think D can help you more than C++ here.
Can you explain better what the problem is and what kind of

for real!,

See here, Unfortunately it's called L not r:

Note that 'real' is a built in type in D. It's an 80-bit float on x86
procs and 64-bit elsewhere.
So .5L is like cast(real).5. Not the solution you were looking for.

This is one of the reasons why something like
std::numeric_limitstype::function() exists.
Which makes a generic and *clean* numeric code in C++

No, they are for structs, not classes.
I had a bit more of a play, and it seems that the scope object is on the

That r for real! was joke.
What i mean is a
so:
When i have the code :
scalar m = 0.5fp;
I want compiler to implicitly cast it to typeof(scalar).
so when the scalar is float, m will be 0.5f.
I am starting to understand, sorry if I am a dumb bear :-) Programming in C++/D
is usually much less hard than understanding humans.

I think you would end up creating a scalar class/struct with operator
overloading to get the behavior you are looking for. I realize that is
more overhead than what you would want but I don't see another way.

Oh... wait a second.
In http://www.digitalmars.com/d/2.0/float.html :
Regardless of the type of the operands, floating point constant folding
is done in real or greater precision. It is always done following IEEE 754
rules and round-to-nearest is used.

With one exception yes, i want all 3 test pass with your fix to implicit
cast.
You know, we are trying to write generic code.
Thanks!
