| /* Note: MIN, MAX are also defined in <sys/param.h> on some systems | |
| (glibc, IRIX, HP-UX, OSF/1). Therefore you might get warnings about | |
| MIN, MAX macro redefinitions on some systems; the workaround is to | |
| #include this file as the last one among the #include list. */ | |
| /* Before we define the following symbols we get the <limits.h> file | |
| since otherwise we get redefinitions on some systems if <limits.h> is | |
| included after this file. Likewise for <sys/param.h>. | |
| If more than one of these system headers define MIN and MAX, pick just | |
| one of the headers (because the definitions most likely are the same). */ | |
| /* Note: MIN and MAX should be used with two arguments of the | |
| same type. They might not return the minimum and maximum of their two | |
| arguments, if the arguments have different types or have unusual | |
| floating-point values. For example, on a typical host with 32-bit 'int', | |
| 64-bit 'long long', and 64-bit IEEE 754 'double' types: | |
| MAX (-1, 2147483648) returns 4294967295. | |
| MAX (9007199254740992.0, 9007199254740993) returns 9007199254740992.0. | |
| MAX (NaN, 0.0) returns 0.0. | |
| MAX (+0.0, -0.0) returns -0.0. | |
| and in each case the answer is in some sense bogus. */ | |
| /* MAX(a,b) returns the maximum of A and B. */ | |
| /* MIN(a,b) returns the minimum of A and B. */ | |
