B.bits(n)

Read（228） Label: bit value, sequence,

Description:

The inverse operation of A.bits() function; get value of the nth bit.

Syntax:

B.bits(n)

Note:

The function gets value of the nth bit; it is the inverse operation of A.bits() function.

Parameter:

B

The value returned by A.bits()

n

An integer representing the nth bit

Option:

@b

Judge whether value of the nth bit in sequence B is 1; the function returns true when the bit value is 1; and returns false when it is 0

Return value:

0/1/Boolean

Example:

 

A

 

1

=192.(rand(2))

Randomly generate a sequence of binary bits.

2

=A1.bits()

Convert A1 to a sequence of long numeric values. For instance:

3

=A2.bits(61)

Return 1.

4

=A2.bits@b(61)

Judge whether the 61th bit member of A2’s sequence is 1 and return true

5

=192.(A2.bits(~))

Return same result as A1 does.
