8.135 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 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. - 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. - See also:
