Unsigned decimal representation of stored integer of fi object




dec(a) returns the stored integer of fi object a in unsigned decimal format as a character vector. dec(a) is equivalent to a.dec.

Fixed-point numbers can be represented as

real-world value=2fraction length×stored integer

or, equivalently as

real-world value=(slope×stored integer)+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.


The code

a = fi([-1 1],1,8,7);
y = dec(a)
z = a.dec


y =

		128   127

z =

		128   127
