exponentmax

Maximum exponent for quantizer object

Syntax

exponentmax(q)

exponentmax(q) returns the maximum exponent for quantizer object q. When q is a fixed-point quantizer object, it returns 0.

q = quantizer('double');
exponentmax(q)

ans =

        1023

For floating-point quantizer objects,

$E_{m a x} = 2^{e - 1} - 1$

For fixed-point quantizer objects, $E_{m a x} = 0$ by definition.
