*To*: srfi-77@xxxxxxxxxxxxxxxxx*Subject*: div0 and mod0*From*: Bradley Lucier <lucier@xxxxxxxxxxxxxxx>*Date*: Tue, 25 Jul 2006 14:15:02 -0400*Cc*: Bradley Lucier <lucier@xxxxxxxxxxxxxxx>*Delivered-to*: srfi-77@xxxxxxxxxxxxxxxxx

div0 and mod0 1. appear in no other programming languages of which I am aware; 2. appear in no implementations of scheme of which I am aware; 3. are useful in no algorithms of which I am aware; 4. appear in no R*RS; 5. are implemented in no computer architectures of which I am aware.

Rationale: The half-open symmetry about zero is convenient for somepurposes.

quotient and remainder 1. appear in every programming language of which I am aware; 2. appear in all implementations of scheme of which I am aware; 3. are useful in many algorithms; 4. appear in every RNRS at least since N=1;

Well, no rationale is given, only the bald statement

The quotient, remainder, and modulo procedures were removed.
