Language Reference

IBCLR(I, POS)

Clears one bit to zero.

I

must be of type integer.

POS

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

Class

Elemental function

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/).
