BIT_SIZE (integer)

  Class:  Inquiry function - Generic

  Returns the number of bits in an integer type.

  The result value is the number of bits ("s") defined by the bit
  model for integers with the kind type parameter of the argument.
  For information on the bit model, see the HP Fortran for OpenVMS
  Language Reference Manual.

  Example:

  BIT_SIZE (1_2) has the value 16 because the INTEGER*2 type contains
  16 bits.
