# IBITS

Elemental Intrinsic Function (Generic): Extracts a sequence of bits (a bit field).

result = IBITS (i,pos,len)

i | (Input) Must be of type integer.
pos | (Input) Must be of type integer. It must not be negative and pos+ len must be less than or equal to BIT_SIZE(i). The rightmost (least significant) bit of i is in position 0.
len | (Input) Must be of type integer. It must not be negative.

## Results

The result type and kind are the same as i. The result has the value of the sequence of len bits in i, beginning at pos, right-adjusted and with all other bits zero.

For more information, see Bit Functions.

The model for the interpretation of an integer value as a sequence of bits is shown in Model for Bit Data.

Specific Name | Argument Type | Result Type
--- | --- | ---

KIBITS | INTEGER(8) | INTEGER(8)
1 Or HBITS

## Example

IBITS (12, 1, 4) has the value 6.

IBITS (10, 1, 7) has the value 5.
