`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 90 and later, has overloads that are GNU extensions

*Class*:Elemental function

*Syntax*:`RESULT = ISHFT(I, SHIFT)`
