exponentmax

Maximum exponent for quantizer object

Syntax

exponentmax(q)


Description

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

Examples

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

ans =

        1023

Algorithms

For floating-point quantizer objects,

$$E_{max}=2^{e-1}-1$$

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