IALL(3f)

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

STANDARD
Fortran 2008 and later

CLASS
Transformational function

SYNTAX

RESULT = IALL(ARRAY[, MASK]) RESULT = IALL(ARRAY, DIM[, MASK])

ARGUMENTS

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.

RETURN VALUE
The result is of the same type as ARRAY.

If DIM is absent, a scalar with the bitwise ALL of all elements in ARRAY is returned. Otherwise, an array of rank n-1, where n equals the rank of ARRAY, and a shape similar to that of ARRAY with dimension DIM dropped is returned.

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
