Result Value

• If X is of type integer, the number of the significant digits of X is:

      type                    bits
  -----------                ------
   integer(1)                   07
   integer(2)                   15
   integer(4)                   31
   integer(8)                   63
  

• If X is of type real, the number of significant bits of X is:

     type                    bits
  ----------                ------
  real(4)                      24
  real(8)                      53
  real(16)                    106
