Syntax

b = bin(a)

Description

b = bin(a) returns the stored integer of fi object a in unsigned binary format as a character vector.

Fixed-point numbers can be represented as

$r e a l - w o r l d v a l u e = 2^{- f r a c t i o n l e n g t h} \times s t o r e d i n t e g e r$

or, equivalently as

$r e a l - w o r l d v a l u e = (s l o p e \times s t o r e d i n t e g e r) + b i a s$

The stored integer is the raw binary number, in which the binary point is assumed to be at the far right of the word.

Tip

bin returns the unsigned binary representation of the stored integer of a fi object. To obtain the binary representation of the real-world value of a fi object, use dec2bin.

Create a signed fi object with values -1 and 1, a word length of 8 bits, and a fraction length of 7 bits.

a = fi([-1 1], 1, 8, 7)

a = 
   -1.0000    0.9922

          DataTypeMode: Fixed-point: binary point scaling
            Signedness: Signed
            WordLength: 8
        FractionLength: 7

Find the unsigned binary representation of the stored integers of fi object a.

b = bin(a)

b = 
'10000000   01111111'
