Syntax

double(a)

Description

double(a) returns the real-world value of a fi object in double-precision floating point. double(a) is equivalent to a.double.

Fixed-point numbers can be represented as

real-world value=2fraction length×stored integer

or, equivalently as

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

Examples

The code

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

returns

y =

           -1      0.9922
z =

           -1      0.9922
