Sevaluator

A simple expression evaluator, generated with flex & bison. Sevaluator invokes GMP library to support large number.

usage example (see test.c):

#include "sevaluator.h"
#include <stdio.h>
#include <stdlib.h>

int main() {
    char *output;
    HistoryList *hist_list = sevaluator_history_create();

    sevaluator_calc("10 + 3 * 3 / 2", &output, list, 5)
    printf("%s\n", output);

    sevaluator_calc("-√(216+3*123/√(1243-452))", &output, list, 5)
    printf("%s\n", output);

    sevaluator_calc("(ans) * 2", &output, list, 5)
    printf("%s\n", output);

    sevaluator_calc("hist[0] * 2", &output, list, 5)
    printf("%s\n", output);

    free(output);
    sevaluator_history_destory(hist_list);
    return 0;
}

Expected output:

29/2
-15.137
