ISHFT — Shift bits#
-
ISHFT()#
ISHFT
returns a value corresponding toI
with all of the bits shiftedSHIFT
places. A value ofSHIFT
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 ofSHIFT
is greater thanBIT_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.- Parameters
I – The type shall be
INTEGER
.SHIFT – The type shall be
INTEGER
.
- Returns
The return value is of type
INTEGER
and of the same kind asI
.
