Description

The BITCLEAR() function clears the specified bit <expN2> in a numeric value <expN1> and returns the new value. If <expN1> and <expN2> are not integers, they will be converted to integer values before the clear takes place. The bit position, <expN2>, can range from 0 (rightmost bit) to 31.


Example

x = 6			&& 0110
y = 1
? bitclear(x,y)
         4		&& 0100
