9.149 ISHFT — Shift bits

Description:

ISHFT returns a value corresponding to I with all of the bits shifted SHIFT places. 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. If the absolute value of SHIFT is greater than BIT_SIZE(I), the value is undefined. Bits shifted out from the left end or right end are lost; zeros are shifted in from the opposite end.

Standard:

Fortran 95 and later

Class:

Elemental function

Syntax:

RESULT = ISHFT(I, SHIFT)

Arguments:

I	The type shall be INTEGER.
SHIFT	The type shall be INTEGER.

Return value:

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