Hi Guatam--

    One way is to change languages .  The RANDOM() built-in function
in PL/I for OS/2 returns a FLOAT BINARY(53) [IEEE long floating point]
value "uniformly distributed between 0 and 1, with 0 < random(x)
< 1."

    Seriously, convert the whole number returned by rand() to a floating
point number within the limits you wish by casting the returned result
to floating point and then dividing by RAND_MAX (RAND_MAX is defined in
stdlib.h), as in:

      #include 
      #include 
      
      int main(void)
      {
          int i;
          for (i=1; i<20; i++)
              printf("%g\n",((float)rand())/RAND_MAX);
      }
