iany

Description

Reduces with bitwise or (inclusive or) 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 = iany(array[, mask])
result = iany(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 11 to nn, where nn 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 OR of all elements in array is returned. Otherwise, an array of rank n1n-1, where nn equals the rank of array, and a shape similar to that of array with dimension dim dropped is returned.

Example

program test_iany
  integer(1) :: a(2)

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

  ! prints 01101110
  print '(b8.8)', iany(a)
end program
