[boost] Naming integer, real and either template types

I am writing template math functions.

Some can take integral types (only)

Some can take real (both built-in floating-point - float, double.. AND User
Defined real types)

And some can take either integral OR real.

Real            : Floating-point types
Integer         : Integral types
Arithmetic      : Either Integral OR Floating-point types

Arithmetic is a bit long - other ideas?

So to write a function something like

template <class RealType>
RealType students_t(ArithmeticType degrees_of_freedom, RealType t)
{ ...
}

Using just T is not an option because there are three (at least) possibles.

What names should I use for the types?

RealType, real_type, RealT, or RT, or ???

IntType, int_type, IntT, IT, or ???

ArithmeticType, arithmetic_type, ArithType, arith_type, AT ???

Suggestions for names please. Rationales? Prior art?  Precedents? Standards?

Thanks

Paul
