ISHFTC — Shift bits circularly#

ISHFTC()#

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).

Parameters

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).

Returns

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

Standard:

Fortran 90 and later, has overloads that are GNU extensions
