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.
