That has been implemented in cinterval.h. You can use the two attached patches to make the changes.

Thanks! I have applied them without problems.

Do you have a priori information on the type of exponents that occur in your computations? For example, if you knew that only integer exponents occurred then you could replace all calls of pow(Z,P) (Z,P: cintervals) by calls of power(Z,n) (Z: cinterval; n:integer).

No, we do not have this knowledge a priori. Of course we can test the type of the exponent at run-time and then invoke the appropriate function.

At the moment, we do not plan to change the pow function.

Well, OK. Thanks again
