IShft Intrinsic

     IShft(I, Shift)

IShft: INTEGER function, the KIND= value of the type being that of argument I.


Shift: INTEGER; scalar; INTENT(IN).

Intrinsic groups: mil, f90, vxt.


All bits representing I are shifted Shift places. Shift.GT.0 indicates a left shift, Shift.EQ.0 indicates no shift and Shift.LT.0 indicates a right shift. If the absolute value of the shift count is greater than BIT_SIZE(I), the result is undefined. Bits shifted out from the left end or the right end are lost. Zeros are shifted in from the opposite end.

See IShftC Intrinsic, for the circular-shift equivalent.
