new .net floating point types for x64?

Question

Does anybody know if there are any? I would be interested in a .net floating point type with the range of a double (or greater) combined with the precision of a decimal (or greater). Are there any planned? Anybody interested in speculating as to the usefulness or practicality of a new high-precision, high-range floating point type on x64?

Answer 1

x64 still has the same core .NET libraries as x86 (although there may be some internal changes, especially in the CLI itself). So no: x64 doesn't get anything extra.

There is BigInteger in 4.0, though.
