`IBITS`

— Bit extraction*Description*:`IBITS`

extracts a field of length`LEN`from`I`, starting from bit position`POS`and extending left for`LEN`bits. The result is right-justified and the remaining bits are zeroed. The value of`POS+LEN`

must be less than or equal to the value`BIT_SIZE(I)`

.*Standard*:- Fortran 95 and later
*Class*:- Elemental function
*Syntax*:`RESULT = IBITS(I, POS, LEN)`

*Arguments*:-
`I`The type shall be `INTEGER`

.`POS`The type shall be `INTEGER`

.`LEN`The type shall be `INTEGER`

. *Return value*:- The return value is of type
`INTEGER`

and of the same kind as`I`. *See also*:- BIT_SIZE, IBCLR, IBSET, IAND, IOR, IEOR
