exponentbias

Return the exponent bias for a quantizer

Syntax

• b = exponentbias(q)
  

Description

b = exponentbias(q) returns the exponent bias of the quantizer q. For fixed-point quantizers, exponentbias(q) returns 0.

Examples

• q = quantizer('double'); 
  b = exponentbias(q) 
  

returns the value b = 1023.

Algorithm

For floating-point quantizers, , where e = eps(q), and exponentbias is the same as the exponent maximum.

For fixed-point quantizers, b = 0 by definition.
