exponentmin

Minimum exponent for quantizer object

Syntax

emin = exponentmin(q)


Description

emin = exponentmin(q) returns the minimum exponent for quantizer object q. If q is a fixed-point quantizer object, exponentmin returns 0.

Examples

q = quantizer('double');
emin = exponentmin(q)

emin =

       -1022

Algorithms

For floating-point quantizer objects,

$$E_{min}=-2^{e-1}+2$$

For fixed-point quantizer objects, $$E_{min}=0$$.
