  IFIX (real4-number)

  A function that converts a real number to an integer.

  +------+---------+----------+------------+-------------+
  | Args | Generic | Specific |  Argument  | Result Type |
  +------+---------+----------+------------+-------------+
  |  1   |  IFIX   | IIFIX    | REAL*4     | INTEGER*2   |
  |      |         | JIFIX    | REAL*4     | INTEGER*4   |
  +------+---------+----------+------------+-------------+
  The function returns an INTEGER*4 value if the /I4 command
  qualifier is in effect; otherwise it returns an INTEGER*2 value.

  IIFIX can also be spelled HFIX (to comply with the MIA standard).
