]> Excuse me for forgetting this fact about the ocaml int type. Having been too accustomed to C/C++, I must have conditioned myself into thinking int couldn't possibly be 31 bits. I swear I had learnt it sometime in the past only to forget it :) Thanks for the clarification. On Friday 07 November 2003 05:53, Jacques Garrigue wrote: > Sure, the int type has only 31 bits.
