9.160 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 90 and later, has overloads that are GNU extensions

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.

Specific names:

Name	Argument	Return type	Standard
ISHFTC(A)	INTEGER A	INTEGER	Fortran 90 and later
BSHFTC(A)	INTEGER(1) A	INTEGER(1)	GNU extension
IISHFTC(A)	INTEGER(2) A	INTEGER(2)	GNU extension
JISHFTC(A)	INTEGER(4) A	INTEGER(4)	GNU extension
KISHFTC(A)	INTEGER(8) A	INTEGER(8)	GNU extension
