sdec

Signed decimal representation of stored integer of fi object

Syntax

sdec(a)

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.

sdec(a) returns the stored integer of fi object a in signed decimal format.

The code

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

returns

ans =

    '-128    127'
