If you look at the Fortran 95 standard, you find 

10.5.1 Numeric editing

(6)  On output, with I, B, O, Z, and F editing, the specified value of the
     field width w may be zero.  In such cases, the processor selects the
     smallest positive actual field width that does not result in a field
     filled with asterisks.  The specified value of w shall not be zero
     on input.
