- /* This is a simple program, meant only to show one way to use GMP for this
- sort of thing. There's few features, and error checking is minimal.
- Standard input is read, calc_help() below shows the inputs accepted.
- Expressions are evaluated as they're read. If user defined functions
- were wanted it'd be necessary to build a parse tree like pexpr.c does, or
- a list of operations for a stack based evaluator. That would also make
- it possible to detect and optimize evaluations "mod m" like pexpr.c does.
- A stack is used for intermediate values in the expression evaluation,
- separate from the yacc parser stack. This is simple, makes error
- recovery easy, minimizes the junk around mpz calls in the rules, and
- saves initializing or clearing "mpz_t"s during a calculation. A
- disadvantage though is that variables must be copied to the stack to be
- worked on. A more sophisticated calculator or language system might be
- able to avoid that when executing a compiled or semi-compiled form.
- Avoiding repeated initializing and clearing of "mpz_t"s is important. In
- this program the time spent parsing is obviously much greater than any
- possible saving from this, but a proper calculator or language should
- take some trouble over it. Don't be surprised if an init/clear takes 3
- or more times as long as a 10 limb addition, depending on the system (see
- the mpz_init_realloc_clear example in tune/README). */
