I once saw an article that talked about type conversions using 
the D language.

Type convert integer to exadecimal, binary, but I'm thinking of 
writing an article in my blog but I do not find the site I saw on 
to know more information of the same type as I did below.

void main()
{
   int a=15;

  writefln("O numero %s em binario é %b", a, a);
}

Note that what you are looking for is a library feature:

In fact every type can implement its own specific format handling:

I'm not talking about it so I'm seeing what I've seen and I'm 
looking for things about the integer conversion operators for 
exa, from exa to integer etc ... I saw this once on the 
tutorialspoint site but I went there and I can not find any more 
I know if it was removed.

Just for clarification, what you've originally shown is formatting: no 
type conversion is involved.

For type conversions, this is a must read anyway:

   https://dlang.org/spec/type.html#integer-promotions

(And "Usual Arithmetic Conversions" there.)

However, I think you're talking about literal syntax:

   https://dlang.org/spec/lex.html#integerliteral

which I had attempted to rephrase here:

   http://ddili.org/ders/d.en/literals.html#ix_literals.literal
