IBITS(I, POS, LEN)

Purpose

Extracts a sequence of bits.

Class

Elemental function

Argument type and attributes

I
must be of type integer.
POS
must be of type integer. It must be nonnegative and POS + LEN must be less than or equal to BIT_SIZE (I).
LEN
must be of type integer and nonnegative.

Result type and attributes

Same as I.

Result value

The result has the value of the sequence of LEN bits in I beginning at bit POS, right-adjusted and with all other bits zero.

The bits are numbered from 0 to BIT_SIZE(I)-1, from right to left.

Examples

IBITS (14, 1, 3) has the value 7. See Integer bit model.
