exponentmin

Return the minimum exponent for a quantizer

Syntax

• emin = exponentmin(q)
  

Description

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

Examples

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

returns the value emin = -1022.

Algorithm

For floating-point quantizers, .

For fixed-point quantizers, .
