Purpose

Function to test the value of a specified bit in a numeric value


Syntax

BITTEST(<expN1>,<expN2>)


See Also

BITAND(), BITCLEAR(), BITLSHIFT(), BITNOT(), BITOR(), BITRSHIFT(), BITSET(), BITXOR()


Description

The BITTEST() function tests the value of the specified bit <expN2> in a numeric value <expN1>. If the bit is 1, BITTEST() returns True (.T.), otherwise it returns False (.F.). 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 = 3
z = 2
? bittest (x,y)
.F.
? bittest (x,z)
.T.
