There's few features, and error checking is minimal. 93 Standard input is read, calc_help() below shows the inputs accepted. 94 95 Expressions are evaluated as they're read. If user defined functions 96 were wanted it'd be necessary to build a parse tree like pexpr.c does, or 97 a list of operations for a stack based evaluator. That would also make 98 it possible to detect and optimize evaluations "mod m" like pexpr.c does. 99 100 A stack is used for intermediate values in the expression evaluation, 101 separate from the yacc parser stack. This is simple, makes error 102 recovery easy, minimizes the junk around mpz calls in the rules, and 103 saves initializing or clearing "mpz_t"s during a calculation. A 104 disadvantage though is that variables must be copied to the stack to be 105 worked on. A more sophisticated calculator or language system might be 106 able to avoid that when executing a compiled or semi-compiled form. 107 108 Avoiding repeated initializing and clearing of "mpz_t"s is important. In 109 this program the time spent parsing is obviously much greater than any 110 possible saving from this, but a proper calculator or language should 111 take some trouble over it. Don't be surprised if an init/clear takes 3 112 or more times as long as a 10 limb addition, depending on the system (see 113 the mpz_init_realloc_clear example in tune/README). */ 114 115 116 #include <stdio.h> 117 #include <stdlib.h> 118 #include <string.h> 119 #include "gmp.h" 120 #define NO_CALC_H /* because it conflicts with normal calc.c stuff */ 121 #include "calc-common.h" 122 123 124 #define numberof(x) (sizeof (x) / sizeof ((x)[0])) 125 126 127 void 128 calc_help (void) 129 { 130 printf ("Examples:\n"); 131 printf (" 2+3*4 expressions are evaluated\n"); 132 printf (" x=5^6 variables a to z can be set and used\n"); 133 printf ("Operators:\n"); 134 printf (" + - * arithmetic\n"); 135 printf (" / %% division and remainder (rounding towards negative infinity)\n"); 136 printf (" ^ exponentiation\n"); 137 printf (" ! factorial\n"); 138 printf (" << >> left and right shifts\n"); 139 printf (" <= >= > \\ comparisons, giving 1 if true, 0 if false\n"); 140 printf (" == != < /\n"); 141 printf (" && || logical and/or, giving 1 if true, 0 if false\n"); 142 printf ("Functions:\n"); 143 printf (" abs(n) absolute value\n"); 144 printf (" bin(n,m) binomial coefficient\n"); 145 printf (" fib(n) fibonacci number\n"); 146 printf (" gcd(a,b,..) greatest common divisor\n"); 147 printf (" kron(a,b) kronecker symbol\n"); 148 printf (" lcm(a,b,..) least common multiple\n"); 149 printf (" lucnum(n) lucas number\n"); 150 printf (" nextprime(n) next prime after n\n"); 151 printf (" powm(b,e,m) modulo powering, b^e%%m\n"); 152 printf (" root(n,r) r-th root\n"); 153 printf (" sqrt(n) square root\n"); 154 printf ("Other:\n"); 155 printf (" hex \\ set hex or decimal for input and output\n"); 156 printf (" decimal / (\"0x\" can be used for hex too)\n"); 157 printf (" quit exit program (EOF works too)\n"); 158 printf (" ; statements are separated with a ; or newline\n"); 159 printf (" \\ continue expressions with \\ before newline\n"); 160 printf (" # xxx comments are # though to newline\n"); 161 printf ("Hex numbers must be entered in upper case, to distinguish them from the\n"); 162 printf ("variables a to f (like in bc).\n"); 163 } 164 165 166 int ibase = 0; 167 int obase = 10; 168 169 170 /* The stack is a fixed size, which means there's a limit on the nesting 171 allowed in expressions.
