MIN and MAX in C

stackoverflow.com › questions › 3437404 › min-and-max-in-c

Where are MIN and MAX defined in C, if at all?

They aren't.

What is the best way to implement these, as generically and type safe as possible (compiler extensions/builtins for mainstream compilers preferred).

As functions. I wouldn't use macros like #define MIN(X, Y) (((X) < (Y)) ? (X) : (Y)), especially if you plan to deploy your code. Either write your own, use something like standard fmax or fmin, or fix the macro using GCC's typeof (you get typesafety bonus too) in a GCC statement expression:

 #define max(a,b) \
   ({ __typeof__ (a) _a = (a); \
       __typeof__ (b) _b = (b); \
     _a > _b ? _a : _b; })

Everyone says "oh I know about double evaluation, it's no problem" and a few months down the road, you'll be debugging the silliest problems for hours on end.

Note the use of __typeof__ instead of typeof:

If you are writing a header file that must work when included in ISO C programs, write __typeof__ instead of typeof.

It's also provided in the GNU libc (Linux) and FreeBSD versions of sys/param.h, and has the definition provided by dreamlax.

The min() function returns the lesser of two values. #include <stdio.h> #include <stdlib.h> int main( void ) { int a; a = min( 1, 10 ); printf( "The value is: %d\n", a ); return EXIT_SUCCESS; }

r/c_language on Reddit: Add integer functions min and max to C language?

July 30, 2023 -

The C programming language is missing library functions min and max for integer types. I am not aware of any argument to not provide them, given virtually every programming language providing them.

Relevance

For floats and doubles, fmin and fmax exists, but not for integer types. Other programming language provide them including C++ by std::min and std::max. Several C libraries provide them too, e.g., Linux, SuperLU, Cairo. Stackoverflow has a question with more then 400 upvotes, indicating that this is a real issue.

Add to C language?

Is it worthwhile to write a paper suggesting the addition of min and max? Or is there a reason that their addition has not already happened?

C is not a batteries included language. These are extremely easy to implement using a function or macro. Literally one-liners that are impossible to screw up. The reason why fmin et al exist is that there are eccentricities to floating point types and it's not a simple comparison. For example, is 7 > NAN?

min is an inline function (implemented using GNU C smart macros) which returns the smaller of a and b. They may be any numeric values, either integer or floating point numbers, and they also may be pointers to the same base type. The result has the type of the argument which has greater range ...

MIN() Macro in C Language – Linux Hint

In this example, we create the “a” and “b” variables of type “int” to which we assign an arbitrary value and from which we find the minimum by calling the macro MIN(). We then output the returned value using the printf() function. To do this, we include the “stdio.h” and “param.h” headers and open a main() function of type void.

Then the ‘fmin’ and ‘fmax’ functions are called and the range or subset of the array is passed to them. The ‘fmin’ and ‘fmax’ functions return the minimum or maximum elements respectively. An example of such a type of function is shown below: #include<stdio.h> #include<math.h> int main() { printf("fmax(223, 422) = %f\n", fmax(223, 422)); printf("fmin(9.9, 2.8) = %f\n", fmin(9.9, 2.8)); return 0; }
