Elemental Intrinsic Function (Specific): Logically shifts an integer right by a specified number of bits. This function cannot be passed as an actual argument.
result = SHIFTR (i,shift)
i |
(Input) Must be of type integer. This is the value to be shifted. |
shift |
(Input) Must be of type integer. The value must be nonnegative and <= BIT_SIZE(i). This value is the number of positions to shift. |
The result type and kind are the same as i. The result is the value of i shifted right by shift bit positions. Bits shifted off the right end are lost; zeros are shifted in from the opposite end.
SHIFTR (i, j) is the same as ISHFT (i, -j).
