  IQINT (number)

  A function that returns the largest integer whose absolute value
  does not exceed the absolute value of the argument and has the same
  sign as the argument.
  +------+---------+----------+------------+-------------+
  | Args | Generic | Specific |  Argument  | Result Type |
  +------+---------+----------+------------+-------------+
  |   1  |  IQINT  | IIQINT   | REAL*16    | INTEGER*2   |
  |      |         | JIQINT   | REAL*16    | INTEGER*4   |
  +------+---------+----------+------------+-------------+
  The function returns an INTEGER*4 value if the /I4 command
  qualifier is in effect; otherwise it returns an INTEGER*2 value.
