    Default Character Values Inside of Number Values

    I am curious... the Java API is able to return the apparent String "NaN" as a double value for non-real calculations.

    How can one include characters in a double value?

    Say if you wanted to design an implementation of imaginaries in Java, you would need to be able to have "i" in a value, how can you make 2i a valid Number?

    NaN is not a string, but a constant double value (read the API on Double for the value). There are many implementations on complex number math - google these terms for the examples.

    I have tried using the Double.longBitsToDouble method to convert a character to double but no matter what I pass it, it won't return the character.

    I have tried passing the character's bit value and hexadecimal. Both do not return a letter.

    See the API for double....Double.longBitsToDouble returns a double, not a character.

    But the value NaN prints as "NaN"

    How can you define something as a double value, when it has a character form in print?
