  13. Hi. I'm kind of a beginner in C programming.
  14. I'm trying to write a C program on SPARC under SunOS.
  15. My problem is, it doesn't seem that I can use math functions that deal with floating point variables. For example, if I try to run following code, I get a error message.
  16.  
  17. #include <stdio.h>
  18. #include <math.h>
  19. main()
  20. {
  21.     float a,b;
  22.     b = fabs(a);
  23.     printf("%f",b);
  24. }
  25.  
  26. Could you tell me why? Or solution?
  27. Thanks for reading this. Please e-mail me the solution.
