BITTEST

BITTEST tests the bit number of the integer specified by an expression.

The function returns 1 if the bit is set; it returns 0 if it is not; Bits are counted from right to left. The

number of the rightmost bit is 0.

If expression evaluates to the null value, null is returned. If bit# evaluates to null, the BITTEST

function fails and the program terminates with a run-time error message.

Non integer values are truncated before the operation is performed.
