bitget - Bit at specified position

Syntax

C = bitget(A, bit)

Description

C = bitget(A, bit) returns the value of the bit at position bit in A. Operand A must be an unsigned integer or an array of unsigned integers, and bit must be a number between 1 and the number of bits in the unsigned integer class of A (e.g., 32 for the uint32 class).

Examples

Example 1

The dec2bin function converts decimal numbers to binary. However, you can also use the bitget function to show the binary representation of a decimal number. Just test successive bits from most to least significant:

disp(dec2bin(13))
1101

C = bitget(uint8(13), 4:-1:1)
C =
     1     1     0     1

Example 2

Prove that intmax sets all the bits to 1:

a = intmax('uint8');
if all(bitget(a, 1:8))
   disp('All the bits have value 1.')
   end

All the bits have value 1.
