IALL — Bitwise AND of array elements#

IALL(ARRAY, DIM, MASK)#

Reduces with bitwise AND the elements of ARRAY along dimension DIM if the corresponding element in MASK is TRUE.

Parameters:
  • ARRAY – Shall be an array of type INTEGER

  • DIM – (Optional) shall be a scalar of type INTEGER with a value in the range from 1 to n, where n equals the rank of ARRAY.

  • MASK – (Optional) shall be of type LOGICAL and either be a scalar or an array of the same shape as ARRAY.

Returns:

The result is of the same type as ARRAY.

Standard:

Fortran 2008 and later

Class:

Transformational function

Syntax:
RESULT = IALL(ARRAY[, MASK])
RESULT = IALL(ARRAY, DIM[, MASK])
Example:
PROGRAM test_iall
  INTEGER(1) :: a(2)

  a(1) = b'00100100'
  a(2) = b'01101010'

  ! prints 00100000
  PRINT '(b8.8)', IALL(a)
END PROGRAM
