6.110 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:

F95 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.
