INTEGER FUNCTION ISHFT(I, SHIFT) |
|
Description |
SHIFT is a positive or negative integer whose absolute value is less than or equal to BIT_SIZE(I). A positive value denotes a shift to the left. Bits that are shifted out are lost and zeros are shifted in from the opposite end. The result has the same kind type as I. |

Notes |
The use of negative, short integer (KIND =1 or KIND = 2) values of I gives undefined results. |
