IPARITY — Bitwise XOR of array elements
- Reduces with bitwise XOR (exclusive or) the elements of ARRAY along
dimension DIM if the corresponding element in MASK is
- Fortran 2008 and later
- Transformational function
RESULT = IPARITY(ARRAY[, MASK])
RESULT = IPARITY(ARRAY, DIM[, MASK])
|ARRAY ||Shall be an array of type |
|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 |
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 XOR 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.
INTEGER(1) :: a(2)
a(1) = b'00100100'
a(2) = b'01101010'
! prints 01001110
PRINT '(b8.8)', IPARITY(a)
