Hi, i learnt that it was

implemented in a previous year's GSoC. But i could not find it in the boost package i downloaded(i beg your pardon if i am wrong).

That library has not yet been included into Boost. You might want to view this GSoC 2007 page for Boost: http://code.google.com/soc/2007/boost/about.html Regards, Eugene Wee

there is scope to work on that. One more feature missing in boost is a BigDecimal class.Would it be good idea to implement the BigDecimal class with all their functionalities -overloading all arithmetic,assignement & comparison operators , functions for other basic operations.

Not sure what a "BigDecimal" type is meant to be, but seeing as though there is a potential candidate for a BigInt you could use that to produce an arbitrary precision interface type (this specific implementation will be rational). Some of the other developing projects such as the computational geometry libraries will in the long run require such a capability.
