IBCLR(I, POS)

Purpose

Clears one bit to zero.

Class

Elemental function

Argument type and attributes

I
must be of type integer.
POS
must be of type integer. It must be nonnegative and less than BIT_SIZE (I).

Result type and attributes

Same as I.

Result value

The result has the value of the sequence of bits of I, except that bit POS of I is set to zero.

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

Examples

IBCLR (14, 1) has the result 12.

If V has the value (/1, 2, 3, 4/), the value of IBCLR (POS = V, I = 31) is (/29, 27, 23, 15/).
