NAMEISHFTC - Performs a circular shift of the rightmost bits
SYNOPSISISHFTC ([I=]i, [SHIFT=]shift [,[SIZE=]size])
IMPLEMENTATION
UNICOS, UNICOS/mk, and IRIX systems
STANDARDS
Fortran 90
DESCRIPTION
The ISHFTC intrinsic function performs a circular shift of the
rightmost bits. It accepts the following arguments:
i Must be of type integer.
shift Must be of type integer. The absolute value of shift must
be less than or equal to size.
size Must be of type integer. The value of size must be positive
and must not exceed BIT_SIZE(i). If size is absent, it is
as if it were present with the value of BIT_SIZE(i).
ISHFTC is an elemental function. The name of this intrinsic cannot be
passed as an argument.
RETURN VALUES
The result type and type parameter are the same as i. The result has
the value obtained by shifting the size rightmost bits of i circularly
by shift positions. If shift is positive, the shift is to the left;
if shift is negative, the shift is to the right; and if shift is zero,
no shift is performed. No bits are lost. The unshifted bits are
unaltered. The bit model defines the interpretation of an integer
value as a sequence of bits. For more information on the model, see
the MODELS(3I) man page.
EXAMPLES
ISHFTC(3, 2, 3) has the value 5.
