exponentmin

Minimum exponent for quantizer object

Syntax

emin = exponentmin(q)

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

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

emin =

       -1022

For floating-point quantizer objects,

$E_{m i n} = - 2^{e - 1} + 2$

For fixed-point quantizer objects, $E_{m i n} = 0$ .
