8.135 ISHFTC — Shift bits circularly

Description:
ISHFTC returns a value corresponding to I with the rightmost SIZE bits shifted circularly SHIFT places; that is, bits shifted out one end are shifted into the opposite end. A value of SHIFT greater than zero corresponds to a left shift, a value of zero corresponds to no shift, and a value less than zero corresponds to a right shift. The absolute value of SHIFT must be less than SIZE. If the SIZE argument is omitted, it is taken to be equivalent to BIT_SIZE(I).
Standard:
Fortran 95 and later
Class:
Elemental function
Syntax:
RESULT = ISHFTC(I, SHIFT [, SIZE])
Arguments:

I The type shall be INTEGER.
SHIFT The type shall be INTEGER.
SIZE (Optional) The type shall be INTEGER; the value must be greater than zero and less than or equal to BIT_SIZE(I).

Return value:
The return value is of type INTEGER and of the same kind as I.
