Return Value

Example
This example prints “The minimum number is 5.000000”:
#include <stdlibh>
#include <stdioh>
int main(void)
{
double r, x, y;
x = 5.0;
y = 7.0;
r = _min(x, y);
printf("The minimum number is %f.", r);
}
#include <stdlibh>
<arith_type> _min(<arith_type> expr1, <arith_type> expr2);
