exponentlength - Exponent length of quantizer object

Syntax

e = exponentlength(q)

Description

e = exponentlength(q) returns the exponent length of quantizer object q. When q is a fixed-point quantizer object, exponentlength(q) returns 0. This is useful because exponent length is valid whether the quantizer object mode is floating point or fixed point.

Examples

q = quantizer('double');
e = exponentlength(q)

e =

    11

Algorithm

The exponent length is part of the format of a floating-point quantizer object [w e]. For fixed-point quantizer objects, e = 0 by definition.
