Returns nonzero if fpval is finite

#include <stdio.h> #include <math.h> int main(void) { printf("isfinite(-1.0) %d\n", isfinite(-1.0)); printf("isfinite(1.0) %d\n", isfinite(1.0)); printf("isfinite(1.0/0.0) %d\n", isfinite(1.0/0.0)); return 0; } /* isfinite(-1.0) 1 isfinite(1.0) 1 isfinite(1.0/0.0) 0 */
