    suppressing leading zero

    Code:
    /*
    I am attempting to print out a float without a leading zero if it's a 
    */
    float number = .2
    
    /*
    I thought just by specifying the following that this would take care of this:
    */
      float val=.2;
      printf("val = [%7.1f]\n",val);
    
    /*
    However the output that I receive is:
    */
    val = [    0.2]
    
    /*
    As a work around I wrote the following code:
    */
      char buffer[10];
      float val=.2;
      char *dp;
    
      sprintf(buffer,"% 7.1f",val);
      dp = strchr(buffer,'.');
      if( dp && !strncmp(dp-2," 0",2) )
         *(dp-1)=' ';
      printf("val = [%s]\n",buffer);
    
    /*
    And I received the desired output of:
    */
    val = [     .2]
    
    /*
    Is there an simpler way to do this imploring a format specifier that I am somehow overlooking?
    */
