Sun Studio 12: Fortran Library Reference

1.4.4.1 Usage: and, or, xor, not, rshift, lshift

For the intrinsic functions:

x = and( word1, word2 )

x = or( word1, word2 )

x = xor( word1, word2 )

x = not( word )

x = rshift( word, nbits )

x = lshift( word, nbits )

word, word1, word2, nbits are integer input arguments. These are intrinsic functions expanded inline by the compiler. The data type returned is that of the first argument.

No test is made for a reasonable value of nbits.

Example: and, or, xor, not:


demo% cat tandornot.f
        print 1, and(7,4), or(7,4), xor(7,4), not(4)
 1      format(4x ’and(7,4)’, 5x ’or(7,4)’, 4x ’xor(7,4)’,
     1         6x ’not(4)’/4o12.11)
        end
demo% f95 tandornot.f
demo% a.out
    and(7,4)     or(7,4)    xor(7,4)      not(4)

Example: lshift, rshift:


demo% cat tlrshift.f
       integer*4 lshift, rshift
       print 1, lshift(7,1), rshift(4,1)
 1     format(1x ’lshift(7,1)’, 1x ’rshift(4,1)’/2o12.11)
       end
demo% f95 tlrshift.f
demo% a.out
 lshift(7,1) rshift(4,1)
