oct

Octal representation of stored integer of fi object

Syntax

b = oct(a)

Description

b = oct(a) returns the stored integer of fi object a in octal format as a character vector.

Fixed-point numbers can be represented as

$$real\text{-}worldvalue=2^{-fractionlength}\times storedinteger$$

or, equivalently as

$$real\text{-}worldvalue=(slope\times storedinteger)+bias$$

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

Examples

View Stored Integer of fi Object in Octal Format

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=1×2 object
   -1.0000    0.9922

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

Find the octal representation of the stored integers of fi object a.
